, was founded in 1984 and purchased by Maxim Integrated Products for $2.5 billion in 2001. Both the Maxim and Dallas Semiconductor brands were actively used until 2007. Since then, the Maxim name has been used for all new products, though the Dallas Semiconductor brand has been retained for some older products, which can be identified by "DS" at the beginning of their part numbers, for example the 1-Wire communications protocol devices. Notable products by the company included the DS80-series microcontrollers with 8051 instruction set. Dallas Semiconductor devices were still actively produced by Maxim Integrated through June of 2021. In August 2021, Maxim was then acquired by
