The Dallas 1-wire protocol saga

This protocol was developed by Dallas Semiconductor back in 1999 perhaps. It was designed for very low bandwidth devices with the priority on simplifying circuitry.

Dallas was acquired by Maxim around 2001 or so. Maxim was acquired by Analog Devices sometime after that. I haven't bothered to dig to deep into the history, but whatever the case in 2026, Dallas is now part of Analog Devices.
