I2C Primer: What is I2C? (Part 1)

Hamza Salman Afzal - Applications Engineer Sep 2nd 2016
Introduction: The Inter-Integrated Circuit (I2C) bus is a two wire serial interface originally developed by the Phillips Corporation for use in consumer products. It is a bi-directional bus that is easily implemented in any IC process (NMOS, CMOS, bipolar) and allows for simple inter-IC communication. Connections are minimized ...

 

DC2217A - LTC4316 Demo Board | Single I2C/SMBus Address Translator (req. DC590 or DC2026)

Nov 18th 2015
Demonstration circuit 2217A features the LTC®4316 single I2C/SMBus address translator.
