CAHC9541QWRKSRQ1 TI I2C/SMBus Multiplexer | 20-VQFN (2.5x4.5) | 1:4 Channel, 1.65-5.5V

Product Overview

The CAHC9541QWRKSRQ1 is a 1:4 bidirectional translating multiplexer from Texas Instruments, designed for I2C and SMBus applications. It allows voltage level translation between 1.65V and 5.5V, enabling communication between devices operating at different voltage levels. The device features four selectable channels, each capable of connecting a separate I2C bus segment to the main bus. It is housed in a compact 20-VQFN (2.5x4.5) package, making it suitable for space-constrained designs. The CAHC9541QWRKSRQ1 is qualified for automotive applications (AEC-Q100), ensuring reliability in harsh environments.
