PCA9546AD TI I2C Multiplexer | 16-SOIC | 4-Channel, 2.3V-5.5V

Product Overview

The PCA9546AD from Texas Instruments is a 4-channel I2C multiplexer designed for applications requiring multiple I2C buses with the same address. It allows selective connection of up to four I2C slave devices to a single master bus, resolving address conflicts and enabling bus expansion. The device operates over a wide supply voltage range of 2.3V to 5.5V and is housed in a compact 16-SOIC package. With low standby current and active-low reset input, it is ideal for power-sensitive and robust system designs.
