TCA9543ADR TI I2C Switch/Multiplexer | 14-SOIC | 2-Channel, 1.65-5.5V

Product Overview

The TCA9543ADR from Texas Instruments is a 2-channel I2C-bus switch/multiplexer with reset and interrupt logic. It allows voltage level translation between different I2C bus segments, enabling multiple devices with the same address to share a single I2C bus. The device operates from 1.65V to 5.5V and is available in a 14-pin SOIC package.
