I²C Guide

Texas Instruments (TI) has supported the highly efficient I²C BUS® interface with high performance microchips for many years. TI’s I/O expanders, multiplexers, buffers and repeaters can help system designers achieve effective subsystem communications and interfacing using proven I²C devices.

The inter-integrated circuit (I²C) bus consists of two active wires; the bidirectional serial data (SDA) line and the bidirectional serial clock (SCL) line.

TI's I²C portfolio includes TCA, PCA, and PCF technologies.
