PCA9534ADW TI I2C I/O Expander | 16-SOIC | 8-bit, 2.3V-5.5V

Product Overview

The PCA9534ADW from Texas Instruments is a 16-pin CMOS device that provides 8 bits of general-purpose parallel input/output (I/O) expansion for I2C-bus applications. It is designed to operate with a supply voltage range of 2.3V to 5.5V and features an I2C interface with a maximum clock frequency of 400 kHz. The device includes an interrupt output (INT) that can be configured to alert the master on input changes, making it ideal for monitoring and control applications.
