PCA9574PW,118 Description

Short technical summary and product information.

The PCA9574PW,118 is an 8-bit I2C-bus and SMBus low voltage General Purpose Input/Output (GPIO) expander from NXP Semiconductors. Designed for low voltage processor and battery-powered mobile applications, it offers a flexible solution for expanding I/O capabilities with minimal interconnections.

 

This device supports a wide operating voltage range from 1.1V to 3.6V, allowing for voltage level translation in mixed-signal environments. Each of the eight I/O ports can be independently configured as an input or output. The PCA9574PW,118 features a 400kHz clock frequency and includes a reset and interrupt output. The core can operate as low as 1.1V while the I/O bank operates between 1.1V and 3.6V.

 

Packaged in a 16-TSSOP, the PCA9574PW,118 is suitable for surface mount applications. It provides 1mA source and 3mA sink current capabilities. The device defaults to inputs on startup and can be configured via I2C/SMBus commands. Its built-in level shifting feature makes it versatile for interfacing processors running at different voltage levels with I/O devices.
