PCA9539 Datasheet - NXP

PCA9539 16-bit I2C and SMBus low power I/O port

The PCA9539; PCA9539R is a 24-pin CMOS device that provides 16 bits of General Purpose parallel Input/Output (GPIO) expansion with interrupt and reset for I2C-bus/SMBus applications and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. I/O expanders provide a simple so.

PCA9539 Features

* 16-bit I2C-bus GPIO with interrupt and reset

* Operating power supply voltage range of 2.3 V to 5.5 V (3.0 V to 5.5 V for PCA9539PW/Q900 and PCA9539RPW/Q900)

* 5 V tolerant I/Os NXP Semiconductors PCA9539; PCA9539R 16-bit I2C-bus and SMBus low power I/O port with interrupt and reset
