The Great Search: DS18B20 and other 1-Wire interface chip...

What this episode covers

We just wrapped up our breakout board design for the DS2484 (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/DS2484R-T/5020823)an I2C to 1-Wire device, and we had someone ask "what is 1-Wire, and when should I use it?" We'll quickly run through the history of 1-Wire and iButton devices (https://en.wikipedia.org/wiki/1-Wire) then search on DigiKey to find some of the 1-Wire chips that are most common, such as EEPROMs (https://www.digikey.com/short/z58jzbmf), GPIO expanders (https://www.digikey.com/short/zzt3c33m) and - of course - temperature sensors (https://www.digikey.com/short/5985cd9t)!
