Dallas Semiconductor, established in 1984 and later acquired by Maxim Integrated in 2002, which itself was taken over by Analog Devices in 2021, specialized in the design and production of analog, digital, and mixed-signal semiconductors (integrated circuits or ICs). Their portfolio featured communication components (including T/E and Ethernet), microcontrollers, battery management solutions, thermal monitoring and control devices, non-volatile random-access memory, microprocessor supervisory circuits, delay lines, silicon oscillators, digital potentiometers, real-time clocks, temperature-compensated crystal oscillators (TCXOs), as well as proprietary 1-Wire technology products like the iButton.
History
Operating out of Dallas, Texas, Dallas Semiconductor was purchased by Maxim Integrated Products in 2001 for $2.5 billion. The two brands coexisted until 2007, after which new product releases adopted the Maxim name exclusively. Nonetheless, legacy devices bearing the "DS" prefix—especially those utilizing the 1-Wire protocol—continue to carry the Dallas Semiconductor brand.
Among its notable offerings were the DS80-series microcontrollers, which were based on the Intel 8051 architecture. Production of Dallas Semiconductor devices proceeded under Maxim Integrated's management until mid-2021. In August of that year, Analog Devices completed its acquisition of Maxim Integrated.
The facility located in Farmers Branch, Texas served as the base for:
- Dallas Semiconductor (1985–2001)
- Maxim Integrated (2001–2017)
- Qorvo (2017–2023)
- Wolfspeed (2023–present)
