PCA9546APWR TI I2C Multiplexer | 16-TSSOP | 4-Channel, 2.3-5.5V

Product Overview

The PCA9546APWR from Texas Instruments is a 4-channel I2C-bus multiplexer with reset and interrupt logic. It allows voltage level translation between different I2C bus segments, enabling multiple devices with the same address to be connected to a single I2C master. The device operates from 2.3V to 5.5V and is available in a compact 16-TSSOP package.
