PCA9539PW,118 Description

Short technical summary and product information.

The PCA9539PW,118 from NXP Semiconductors is a 16-bit General Purpose Input/Output (GPIO) expander designed for I2C-bus and SMBus applications. It provides a simple solution for systems needing additional I/O for devices such as sensors, LEDs, and push buttons.

 

This device features two 8-bit configuration registers, allowing I/Os to be selected as either inputs or outputs. It includes an open-drain interrupt output that activates when an input state changes, signaling the system master. The PCA9539PW,118 operates over a voltage range of 2.3V to 5.5V and supports a clock frequency of up to 400 kHz. The I/Os are 5V tolerant.

 

Packaged in a 24-TSSOP, the PCA9539PW,118 is designed for surface mounting. It offers features like Power-On Reset (POR) and supports I2C and SMBus interfaces. The device is suitable for applications requiring expanded I/O capabilities in a compact form factor.
