PCA9544ARGYR TI Multiplexer IC | 20-VQFN (3.5X4.5) | 4-Channel, I2C/SMBus

Product Overview

The PCA9544ARGYR from Texas Instruments is a 4-channel I2C-bus multiplexer with interrupt logic and reset functionality. It allows voltage level translation between different I2C-bus segments, enabling communication with multiple devices sharing the same bus address. The device operates from 2.3V to 5.5V and is available in a compact 20-VQFN (3.5x4.5mm) package, ideal for space-constrained applications.
