PCA9545APWT TI I2C Multiplexer | 20-TSSOP | 4-Channel, 2.3-5.5V

Product Overview

The PCA9545APWT 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 communication with multiple devices sharing the same I2C address. Housed in a compact 20-TSSOP package, it operates over a wide supply voltage range of 2.3V to 5.5V, making it suitable for various low-power and industrial applications.
