TCA9543APWR TI I2C Switch/Multiplexer | 14-TSSOP | 2-Channel, 1.65-5.5V

Product Overview

The TCA9543APWR from Texas Instruments is a 2-channel I2C bus switch/multiplexer with interrupt logic and reset functionality. It allows voltage level translation between different I2C bus segments, enabling communication with multiple devices sharing the same I2C address. The device operates from 1.65V to 5.5V and is available in a 14-pin TSSOP package.
