Overview

Texas Instruments Incorporated, commonly known as TI, is a Dallas-based American semiconductor company whose principal business is designing, manufacturing, and selling analog integrated circuits and embedded processing products. Its chips are used in industrial equipment, automotive systems, personal electronics, communications infrastructure, and many other products that require power conversion, signal measurement, sensing, control, or embedded computation. TI also operates the DLP technology business and has maintained a significant education-technology presence through graphing and scientific calculators. The company traces its origins to Geophysical Service Incorporated, founded in 1930 by J. Clarence Karcher and Eugene McDermott to provide seismic exploration services to the petroleum industry. During the Second World War, Geophysical Service expanded into electronics for the United States military. After Cecil H. Green, J. Erik Jonsson, Eugene McDermott, and H. B. Peacock acquired the business in 1941, its electronics and manufacturing activities grew rapidly. In 1951, the electronics-oriented operation was reorganized as Texas Instruments, while Geophysical Service continued as a subsidiary for a period. TI became one of the early commercial forces in semiconductor technology. Gordon Teal developed the company's first commercial silicon transistor in 1954, and TI helped bring transistor radios to consumers through the Regency TR-1. In 1958, TI engineer Jack Kilby demonstrated one of the first working integrated circuits, an achievement that helped establish the foundation of modern electronics. The company later contributed to transistor-transistor logic, digital signal processing, microcontrollers, speech synthesis, radar, infrared systems, and precision-guided weapon technology. TI also built a notable consumer-products business. It developed the Cal-Tech handheld-calculator prototype in 1967, introduced commercial handheld calculators in the early 1970s, and released products such as Speak & Spell and the TI-99/4A home computer. The company subsequently reduced its exposure to consumer computers and defense electronics, selling its defense business to Raytheon in 1997 and its personal-computer business to Acer in the same year. These divestitures reinforced a strategic concentration on semiconductors and related technologies. In 1987, TI invented digital light processing, based on the digital micromirror device. DLP later became important in data projectors, home-theater equipment, and digital cinema. The company strengthened its analog portfolio through the 2011 acquisition of National Semiconductor, combining National's power-management and analog technologies with TI's extensive catalog and customer-support tools. Today, TI's identity is centered on a broad analog and embedded-processing portfolio, long product availability, proprietary manufacturing capacity, and direct support for engineers developing industrial and automotive systems. Its calculators and DLP products remain visible consumer-facing offerings, but semiconductors constitute the core of the brand.

History

Texas Instruments developed from Geophysical Service Incorporated, a seismic-exploration company established in 1930. J. Clarence Karcher and Eugene McDermott created the original business to serve petroleum companies, but its technical capabilities later attracted military electronics work. In 1941, McDermott, J. Erik Jonsson, Cecil H. Green, and H. B. Peacock acquired Geophysical Service. The company's Laboratory and Manufacturing division expanded during the Second World War as it supplied electronic equipment to the United States Army, Army Signal Corps, and Navy. The electronics operation grew faster than the geophysical business. In 1951, the company reorganized and adopted the name Texas Instruments, with Geophysical Service becoming a subsidiary. TI entered semiconductor manufacturing after licensing transistor technology from Western Electric in 1952. Gordon Teal joined the company and led work on semiconductor crystals and silicon devices. In 1954, TI produced a commercial silicon transistor and helped create the Regency TR-1, an early mass-produced transistor radio. These efforts demonstrated the company's strategy of using technological inventions to create new markets rather than serving only as a component supplier. Jack Kilby made one of TI's most consequential contributions in 1958, when he demonstrated a working integrated circuit at the company's Central Research Laboratories. Although Robert Noyce independently developed an important silicon integrated-circuit structure at Fairchild Semiconductor, Kilby's work at TI became a landmark in the development of integrated electronics. TI subsequently commercialized transistor-transistor logic, which helped standardize digital computer circuitry, and expanded into military electronics, radar, infrared imaging, missile guidance, and other advanced systems. The company entered consumer electronics more visibly in the 1960s and 1970s. Kilby and colleagues developed the Cal-Tech handheld-calculator prototype in 1967. TI followed with commercial calculators, including the SR-10 and SR-50, and later became a major producer of scientific and graphing calculators. In 1978, it introduced Speak & Spell, using a speech-synthesis chip capable of electronically reproducing human speech. TI also entered the home-computer market with the TI-99/4 in 1979 and the TI-99/4A in 1981. A price war in the early 1980s contributed to the withdrawal of the home-computer line in 1983. TI developed digital light processing in 1987. The technology used a digital micromirror device and became the basis for projection, home entertainment, and digital-cinema applications. During the same broad period, TI pursued quality-management programs involving statistical process control, Taguchi methods, and Six Sigma practices. Its manufacturing and quality work received the Malcolm Baldrige National Quality Award in 1992. From the 1990s onward, TI increasingly concentrated on semiconductors. The company sold its defense business to Raytheon in 1997 and transferred its personal-computer line to Acer. It also sold most of Geophysical Service to Halliburton in 1988. In 2011, TI acquired National Semiconductor, substantially enlarging its analog and power-management portfolio. The modern company is primarily an analog and embedded-processing manufacturer, supported by internal manufacturing, a large catalog of long-lived products, development tools, and direct relationships with industrial and automotive customers. Calculators and DLP remain important brand touchpoints, while analog chips, embedded processors, power products, data converters, amplifiers, and interface devices form the center of its commercial identity.
