Texas Instruments

Texas Instruments Inc. (NYSE: TXN), widely known as TI, is an American company based in Dallas, Texas, United States,[4] renowned for developing and commercializing semiconductor and computer technology. TI is the No. 3[5] manufacturer of semiconductors worldwide after Intel and Samsung, the No. 2 supplier of chips for cellular handsets after Qualcomm, and the No. 1 producer of digital signal processors (DSPs) and analog semiconductors, among a wide range of other semiconductor products.[6] In 2010, the company was listed at number 223 on the Fortune 500.

Texas Instruments was founded by Cecil H. Green, J. Erik Jonsson, Eugene McDermott, and Patrick E. Haggerty in 1951. McDermott was one of the original founders of Geophysical Service in 1930. McDermott, Green, and Jonsson were GSI employees who purchased the company in 1941 on the day before Pearl Harbor was attacked. In November, 1945, Patrick Haggerty was hired as general manager of the Laboratory and Manufacturing (L&M) division. By 1951, the L&M division, with its defense contracts, was growing faster than GSI's Geophysical division. The company was reorganized and initially renamed General Instruments Inc. Because there already existed a firm named General Instrument, the company was rechristened Texas Instruments that same year. Geophysical Service Inc. became a subsidiary of Texas Instruments which it remained until early 1988, when most of GSI was sold to the Halliburton Company.

Texas Instruments exists to create, make and market useful products and services to satisfy the needs of its customers throughout the world.[7]

– Patrick Haggerty, Texas Instruments Statement of Purpose

Geophysical Service Incorporated

Texas Instruments can trace it roots back to 1930 when Dr. J. Clarence Karcher and Eugene McDermott founded Geophysical Service, a pioneering provider of seismic exploration services to the petroleum industry. In 1939 the company reorganized as Coronado Corp., an oil company with Geophysical Service Inc (GSI), now as a subsidiary. On December 6, 1941, McDermott along with three other GSI employees, J. Erik Jonsson, Cecil H. Green, and H.B. Peacock purchased GSI, During World War II, GSI built electronics for the U.S. Army Signal Corps and the U.S. Navy. After the war GSI continued to produce electronics. The rugged nature of equipment for the oil industry and of military equipment were similar and thus continued expansion into military contracts was a natural progression. In 1951 the company changed its name to Texas Instruments, GSI becoming a wholly owned subsidiary of the new company.

An early success story for TI-GSI came in the 1950s when GSI was able (under a Top Secret government contract) to monitor the Soviet Union's underground nuclear weapons testing from outcrop bedrock found in Oklahoma.[citation needed]

Texas Instruments also continued to manufacture equipment for use in the seismic industry, and GSI continued to provide seismic services. After selling (and repurchasing) GSI, TI finally sold the company to Halliburton in 1988, at which point GSI ceased to exist as a separate entity.

Defense electronics

Texas Instruments was also active in the defense electronics market starting in 1942 with submarine detection equipment, building on the seismic exploration technology developed for the oil industry. This business was known over time as the Laboratory & Manufacturing Division, the Apparatus Division, the Equipment Group and the Defense Systems & Electronics Group (DSEG).

During the 1980s quality became a focus area in this business. During the early 80s a quality program was instituted. This included wide spread Juran training, as well as promoting Statistical process control, Taguchi methods and Design for Six Sigma. In the late 80s TI, along with Eastman Kodak and Allied Signal, began involvement with Motorola institutionalizing Motorola's Six Sigma methodology.[8] Motorola, who originally developed the Six Sigma methodology, began this work in 1982. Note that TI's Six Sigma program began well before 1995 when GE started its legendary Six Sigma policy. In 1992 the DSEG division of Texas Instruments' quality improvement efforts were rewarded by winning the Malcolm Baldrige National Quality Award for manufacturing.

The following are some of the major programs of the former TI defense group.[9]

Radar systems

TI went on to produce side-looking radar systems, the first terrain following radar and surveillance radar systems for both the military and FAA. In 1967 TI demonstrated the first solid-state radar — Molecular Electronics for Radar Applications (MERA). In 1976 TI developed a microwave landing system prototype. In 1984 TI developed the first inverse synthetic aperture radar (ISAR). The first single-chip gallium arsenide radar module was developed. In 1991 the Military Microwave Integrated Circuit (MIMIC) program was initiated – a joint effort with Raytheon.

Infrared systems

In 1956 TI began research on infrared technology that led to several line scanner contracts and with the addition of a second scan mirror the invention of the first forward looking infrared (FLIR) in 1963 with production beginning in 1966. In 1972 TI invented the Common Module FLIR concept, greatly reducing cost and allowing reuse of common components.

An AGM-154 Joint Standoff Weapon.

In 1961 TI won the guidance and control system contract for the defense suppression AGM-45 Shrike anti-radiation missile. This led later to the prime on the high-speed anti-radiation missile (AGM-88 HARM) development contract in 1974 and production in 1981. In 1969 TI won the Harpoon (missile) Seeker contract. In 1986 TI won the Army FGM-148 Javelin fire-and-forget man portable anti-tank guided missile in a joint venture with Martin Marietta. In 1991 TI was awarded the contract for the AGM-154 Joint Standoff Weapon (JSOW).

Military computers

Because of TI's dominance in military temperature range (silicon) transistors and integrated circuits (ICs), TI won contracts for the first IC-based computer for the U.S. Air Force in 1961 and for ICs for the Minuteman Missile the following year. In 1968 TI developed the data systems for Mariner Program. In 1991 TI won the F-22 Radar and Computer development contract.

Laser-guided bombs

In 1964 TI began development of the first laser guidance system for precision-guided munitions (PGM) leading to the Paveway series of laser-guided bombs (LGB)s. The first LGB was the BOLT-117.

Divestiture to Raytheon

As the defense industry consolidated, TI sold its defense business to Raytheon in 1997 for $2.95 billion. The Department of Justice required that Raytheon divest the TI Monolithic Microwave Integrated Circuit (MMIC) operations after closing the transaction.[10] The TI MMIC business accounted for less than $40 million in 1996 revenues, or roughly two percent of the $1.8 billion in total TI defense revenues was sold to TriQuint Semiconductor, Inc. Raytheon retained its own existing MMIC capabilities and has the right to license TI's MMIC technology for use in future product applications from TriQuint.[11]

Shortly after Raytheon acquired TI DSEG, Raytheon then acquired Hughes Aircraft from General Motors Raytheon then owned TI's Mercury Cadmium Telluride detector business and Infrared (IR) systems group. In California, it also had Hughes infrared detector and an IR systems business. When again the US government forced Raytheon to divest itself of a duplicate capability, the company kept the TI IR systems business and the Hughes detector business. As a result of these acquisitions these former arch rivals of TI systems and Hughes detectors work together.[12]

Immediately after acquisition, DSEG was known as Raytheon TI Systems (RTIS).[13] It is now fully integrated into Raytheon and this designation no longer exists.


Early in 1952 Texas Instruments purchased a patent license to produce (germanium) transistors from Western Electric Co., the manufacturing arm of AT&T, for $25 000. By the end of that year, it was already manufacturing and selling them. TI Vice President Patrick Haggerty was the visionary at TI who realized the future of this technology in the electronics industry. Later that year responding to an ad in the New York Times for a research director, Gordon K. Teal was hired by Haggerty. Teal, who worked for Bell Labs at Murray Hill, NJ but was from Dallas, desired to return to his native Texas.

Teal started at TI on January 1, 1953, bringing with him his expertise in growing semiconductor crystals. Haggerty had hired him to establish a team of scientists and engineers to keep TI at the leading edge of the new and rapidly expanding semiconductor industry. Teal's first assignment was to organize what became TI's Central Research Laboratories (CRL). Because of Teal's background, this new department was based on Bell Labs.

Among his new hires was Willis Adcock who joined TI early in 1953. Adcock, who like Teal was a physical chemist, began leading a small research group focused on the task of fabricating "grown-junction silicon single-crystal small-signal transistors. Adcock later became the first TI Principal Fellow.[14]

First silicon transistor

In January 1954, M Tanenbaum et al. at Bell Labs created the first workable silicon transistor. (IEEE Spectrum, May 2004, p 48.) This work was reported in the spring of 1954 at the IRE off-the-record conference on Solid State Devices and later published in the Journal of Applied Physics, 26, 686-691(1955). Working independently in April 1954, Gordon Teal at TI created the first commercial silicon transistor and tested it on April 14, 1954. On May 10, 1954 at the Institute of Radio Engineers (IRE) National Conference on Airborne Electronics, in Dayton, Ohio, Teal revealed this achievement to the world when he announced, "Contrary to what my colleagues have told you about the bleak prospects for silicon transistors, I happen to have a few of them here in my pocket." Teal also presented a paper, "Some Recent Developments in Silicon and Germanium Materials and Devices," at this conference.[15] At this point TI stood alone as the first volume manufacturer of silicon transistors. However, the breakthrough that began the "Silicon Age", occurred in early 1955 when Tanenbaum et al. invented the diffused-base silicon transistor created by solid-state diffusion of impurities, which was later employed to develop integrated circuitry.

In 1954, Texas Instruments designed and manufactured the first transistor radio. The Regency TR1 used germanium transistors, as silicon transistors were much more expensive at the time. This was an effort by Haggerty to increase market demand for transistors.

First integrated circuits
Transistorized "logic" chip, an integrated circuit produced by TI

Jack Kilby, an employee at TI's Central Research Labs, invented the integrated circuit in 1958. Kilby recorded his initial ideas concerning the integrated circuit in July 1958 and successfully demonstrated the world's first working integrated circuit on September 12, 1958.[16] Six months later Robert Noyce of Fairchild Semiconductor (who went on to co-found Intel) independently developed the integrated circuit with integrated interconnect, and is also considered an inventor of the integrated circuit.[17] Kilby won the 2000 Nobel Prize in Physics for his part of the invention of the integrated circuit.[18] Noyce's chip, made at Fairchild, was made of silicon, while Kilby's chip was made of germanium. In 2008 TI announced its new "Kilby Labs", a center of innovation designed to foster new forms of semiconductor technology.[19]

Standard TTL
Texas Instruments and other brands of 7400 series TTL and CMOS logic.

The 7400 series of transistor-transistor logic (TTL) chips, developed by Texas Instruments in the 1960s, popularized the use of integrated circuits in computer logic. The military grade version of this was the 5400 series.


Texas Instruments invented the hand-held calculator in 1967 (they were $2,500 a piece) and the single-chip microcomputer in 1971, and was assigned the first patent on a single-chip microprocessor (invented by Gary Boone) on September 4, 1973.[20] This was disputed by Gilbert Hyatt, formerly of the Micro Computer Company, in August 1990 when he was awarded a patent superseding TI's. This was over-turned on June 19, 1996 in favor of TI.[21] (Note: Intel is usually given credit with Texas Instruments for the almost-simultaneous invention of the microprocessor.)

First speech synthesis chip

In 1978, Texas Instruments introduced the first single-chip LPC speech synthesizer.[22] In 1976 TI began a feasibility study memory intensive applications for bubble memory then being developed. They soon focused on speech applications. This resulted in the development the TMC0280 one-chip Linear predictive coding (LPC) speech synthesizer which was the first time a single silicon chip had electronically replicated the human voice.[9][23] This was used in several TI commercial products beginning with Speak & Spell which was introduced at the Summer Consumer Electronics Show in June 1978. In 2001 TI left the speech synthesis business, selling it to Sensory Inc. of Santa Clara, CA.

Creating a new industry

TI had two interesting problems with engineering and product development after the introduction of the semiconductor and the microprocessor. Firstly, most of the chemicals, machinery and technologies needed to create semiconductors did not exist so TI had to "invent" them.[citation needed] Secondly, the market was small for TI electronic components in the early days so TI had to "invent" uses to create the markets. For example TI created the first transistor radio for this purpose. Another example, TI developed the first wall mounted, computer controlled, home set-back thermostat in the late '70s but nobody would buy it mostly because of its cost. TI started an Industrial Controls division, based in Johnson City, Tennessee, which built automated process control computers used in the chemical and food industry and was very successful. This business was eventually sold to Siemens AG in October, 1991. TI turned to military and government uses and had many electro-mechanical devices used in the Apollo rocket and moon lander.

In 1969 several employees left TI to found IC manufacturer Mostek. In 1988 Cyrix was spun off from Mostek.

Consumer electronics and computers
TI-30 electronic calculator, 1976

TI continued to be active in the consumer electronics market through the 1970s and 1980s. Early on this also included two digital clock models one for desk and the other a bedside alarm. From this sprang what became the Time Products Division with the LED watches. Though these LED watches enjoyed early commercial success thanks to to excellent quality, it was short lived due to poor battery life. LED's were replaced with LCD watches for a short time but these could not compete because of styling issues, excessive makes and models, and price points. The watches were manufactured in Dallas and then Lubbock Texas. In 1978, Texas Instruments introduced the first single chip speech synthesizer and incorporated it in a product called Speak & Spell, which was later immortalized in the movie E.T. the Extra-Terrestrial. Several spinoffs, such as the Speak & Read and Speak & Math, were introduced soon thereafter.

In 1979, TI entered the home computer market with the TI99/4, a competitor to such entries as the Apple II, Tandy/RadioShack TRS-80 and the later Atari 400/800 series, Commodore VIC-20 and Commodore 64. It discontinued the TI-99/4A (1981), the sequel to the 99/4, in late 1983 amidst an intense price war waged primarily against Commodore. At the 1983 Winter CES, TI showed models 99/2 and the Compact Computer 40 (CC-40), the latter aimed at professional users. The TI Professional (1983) ultimately joined the ranks of the many unsuccessful DOS and x86-based—but non-compatible—competitors to the IBM PC. (The founders of Compaq, an early leader in PC compatibles, all came from TI.) The company for years successfully made and sold PC-compatible laptops before withdrawing from the market and selling its product line to Acer in 1997.

Artificial intelligence

TI was active in the 1980s in the area of Artificial Intelligence. It developed and sold the Explorer computer family of Lisp Machines. For the Explorer a special 32bit Lisp microprocessor was developed, which was used in the Explorer II and the TI MicroExplorer (a Lisp Machine on a Nubus board for the Apple Macintosh).

Sensors and controls

Texas Instruments was a major OEM of sensor, control, protection, and RFID products for the automotive, appliance, aircraft, and other industries. The S&C division was headquartered in Attleboro, Massachusetts.

In 2006, Bain Capital LLC, a private equity firm, purchased the Sensors & Controls division for $3.0 billion in cash.[24] The RFID portion of the division remained part of TI, transferring to the Application Specific Products business unit of the Semiconductor division, with the newly formed independent company based in Attleboro taking the name Sensata Technologies.


TI sold its software division (along with its main product, the IEF) to Sterling Software in 1997. It is now part of Computer Associates. TI still owns small pieces of software though, i.e. software for calculators like TI Interactive!. TI also creates a significant amount of target software for its Digital Signal Processors, along with host based tools for creating DSP applications.

TI today

Today, TI is made up of two main divisions: Semiconductors (SC) and Educational Technology (ET).


Semiconductor products account for approximately 96 percent of TI's revenues. TI has a market leading position in many different product areas, including digital signal processors in the TMS320 series, high speed digital-to-analog and analog-to-digital converters, power management solutions, and high performance analog circuits. Wireless communications has been a primary focus for TI, with around 50 percent of all cellular phones sold worldwide containing TI chips. TI also manufactures other semiconductor products, ranging from application-specific integrated circuits to microcontrollers.

Wireless Business Unit

TI’s Wireless Business Unit (WBU) offers solutions that support consumer-demanded devices across a variety of markets – from smartphones and eBooks, to tablets, consumer electronics and other portable devices. With a long legacy in the mobile market, TI’s OMAP applications processor family and wireless connectivity solutions place TI as a leading silicon provider for mobile and consumer devices. For more information on TI’s wireless focus areas, see www.ti.com/wireless. Viewpoints on the latest mobile trends and news are also provided on TI’s Mobile Momentum blog, http://ti.com/mobilemomentum.

Mixed Signal Automotive

MSA (Mixed Signal Automotive) is a business unit within High Volume Analog and Logic SBE that manufactures mixed signal and analog solutions for automotive applications. MSA offers a variety of devices for the Transportation and Automotive Market. In the power space: DC/DC Controllers and Converters, LDOs (Low Dropout Voltage Regulators), Voltage References and Voltage Supervisors. In the networking space, MSA has solutions for CAN and LIN. Safety-related solutions include airbags and anti-lock braking.

Technology Development and Manufacturing

Today, TI's internal semiconductor manufacturing operations span eight countries and include more than 3.5 million square feet of clean room space across 17 factories that fabricate, assemble, test and package billions of analog, embedded processing and wireless products each year. For more information on TI's manufacturing and technology development, visit ti.com/manufacturing.

Application Specific Products

Another business unit of the Semiconductor division called Application Specific Products (ASP) develops specific products that cater to a broad range of DSP applications, such as digital still cameras, cable modems, Voice over IP (VOIP), streaming media, speech compression and recognition, wireless LAN and gateway products (residential and central office), and RFID.


TI is the sole source for digital light processing micro-mirror components, a technology used in video projectors and televisions as well as movie theatres or cinemas.

On February 2, 2000, Philippe Binant, technical manager of Digital Cinema Project at Gaumont in France, realized the first digital cinema projection in Europe[25] with the TI mark V prototype projector.


Texas Instruments has a very wide range of microcontrollers.[26]

Most of the older DSPs are still available through.

Multi-core processors

OMAP systems-on-chips (SoC's) are designed for low-powered applications, originally mobile phones. As a rule they contain an ARM application processor (currently Cortex-A8, previously ARM11 or ARM9), a DSP (currently C64x, previously often C55), and sometimes other cores.
DaVinci SoC's contain a C64 series DSP core, an ARM9 core for applications processing, and specialized video processing peripherals.


TI has always been among the Top 10 of the semiconductor sales leaders. In 2005, TI was number 3, after Intel and Samsung, and ahead of Toshiba and STMicroelectronics. For more information, refer to the Semiconductor sales leaders by year. Some of its main competitors include Microchip Technology, Cypress Semiconductor, Integrated Device Technology, Qualcomm, Samsung Electronics, and Xilinx.

TI has the largest market share in the analog semiconductor industry which has an estimated market TAM exceeding US$37 Billion. TI is reported to have 14% of the market, leading ahead of competitors ST Microelectronics, Infineon and NXP Semiconductors according to latest reports[27] from Gartner.

TI E2E Community

In 2008, Texas Instruments launched its E2E Community, a place for engineers from all over the world to discuss and find support for their electronic design projects.

Educational technology

Texas Instruments is also notable for its calculator range, the TI-30 being one of the most popular early calculators. TI has also developed a line of graphing calculators, the first being the TI-81, and most popular being the TI-83 Plus (with the TI-84 Plus being an updated equivalent). TI is often seen as the competitor to Hewlett-Packard in this regard, with fierce loyalties often arising.

TI calculator community

In the 1990s, with the advent of TI's graphing calculator series, programming became popular among some students. The TI-8x series of calculators (beginning with the TI-81) came with a built-in BASIC interpreter, through which simple programs could be created. The TI-85 was the first TI calculator to allow assembly programming (via a shell called "ZShell"), and the TI-83 was the first in the series to receive native assembly. While the earlier BASIC programs were relatively simple applications or small games, the modern assembly-based programs rival what one might find on a Game Boy or PDA.[citation needed]

Around the same time that these programs were first being written, personal web pages were becoming popular (through services such as Angelfire and GeoCities), and programmers began creating websites to host their work, along with tutorials and other calculator-relevant information. This led to the formation of TI calculator webrings, and eventually a few large communities, including the now-defunct TI-Files, and active ticalc.org. Ticalc.org is now seen as the authoritative source for programming for TI calculators, and at the site, one can find thousands of applications (including games, educational programs, and even simple operating environments), programming tutorials, calculator news, and discussion forums, among other things.

TI graphing calculators generally fall into two distinct groups, those powered by the Zilog Z80 and those running on the Motorola 68000 series. Although a derivative of the Z80 was in the original Game Boy, the 68000 is far more powerful, and therefore better suited for gaming and processor intensive applications.

Both these lines of calculators are locked by TI to disable use of custom flash applications and custom operating systems (standard applications are however freely usable), through the signing of this software, with checks in the hardware. However the keys used were found by brute force and published in 2009, after which TI began sending invalid DMCA-takedown notices, causing the Texas Instruments signing key controversy. However at least one of the receivers filed a DMCA Section 512 counter-notice, to which TI has not responded, and the keys are now available again. Enthusiasts had already been creating their own operating systems before the finding of the keys, which could be installed with other methods.[28]

The TI-84 Plus Silver Edition comes preloaded with a variety of student-oriented apps, including App4Math, a computer algebra system developed for the calculator.

A recent development are the models of the TI-Nspire family, which reached the market in fall 2007. These models integrate seamlessly various mathematical software environments and are available as handhelds as well as software.

There is an ongoing debate among financial calculator fans as to whether the popular TI BA II Plus is superior to the iconic Hewlett Packard HP-12C from 1981. The TI BA II Plus continues to maintain popularity due to its simple and intuitive layout compared to the HP 12c (which uses reverse polish notation). The TI BA II Plus and the TI BA II Plus Professional version are two of only four calculators permissible in the Chartered Financial Analyst exams. (The others being the HP-12C and the HP-12C Platinum.) [29]

There are many TI calculators still selling without graphing capabilities.[30] The TI-30 has been replaced by the TI-30X IIS.There are even some financial calculators for sale on the TI website.

Industry recognition

In 2007, Texas Instruments was awarded the Manufacturer of the Year for Global Supply Chain Excellence by World Trade magazine.[31]

A more complete list of TI's awards and recognition can be found here.

Values and ethics

Texas Instruments is known to uphold values and is considered highly ethical. In five consecutive years (2007 through 2011), TI made it to the list of most ethical companies in the world,[32][33][34][35][36] compiled by Ethisphere Institute. TI is the only company to appear in all five years' lists in the Electronics/Semiconductor category.


In 1997 Texas Instruments acquired Amati Communications for $395 million[37]
In 1998 TI acquired GO DSP [38]
In 1999 Butterfly VLSI, Ltd was acquired for approx. $50 million[39]
In 1999 Telogy Networks for $457 million[40]
In 2000 TI acquired Burr-Brown Corporation for $7.6 billion[41]
In 2009 Luminary Micro was acquired [42][43]

National Semiconductor acquisition

On April 4, 2011, Texas Instruments announced that it has agreed to buy National Semiconductor for $6.5 billion in cash. Texas Instruments will pay $25 per share of National Semiconductor stock. This is an 80% premium over the share price of $14.07 as of April 4, 2011 close. The deal would make Texas Instruments one of the world's largest makers of analog technology components.[3][44][45][46][47]
