PCA9545ARGYR TI I2C Switch/Multiplexer | 20-VQFN (3.5x4.5) | 4-Channel, 1-of-4

Product Overview

The PCA9545ARGYR from Texas Instruments is a 4-channel I2C-bus switch/multiplexer with reset functionality. It allows voltage level translation between different I2C bus segments, enabling connection of multiple I2C devices with different supply voltages. The device is controlled via the I2C bus and supports up to 4 selectable channels, each with its own I2C bus. It operates from 2.3V to 5.5V and is available in a compact 20-VQFN (3.5x4.5mm) package, making it ideal for space-constrained applications.
