PCA9543APWR TI I2C Multiplexer | 14-TSSOP | 2-Channel, 1.65-5.5V

Product Overview

The PCA9543APWR from Texas Instruments is a 2-channel I2C multiplexer designed for voltage-level translation and bus isolation. It allows multiple I2C devices with different voltage levels to communicate on a single bus. The device operates from 1.65V to 5.5V and features active-low reset input, making it ideal for multi-voltage systems.
