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

PCA9539 Description

PCA9539; PCA9539R 16-bit I2C-bus and SMBus low power I/O port with interrupt and reset Rev.9 * 8 November 2017 Product data sheet 1.Gene.
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.

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

PCA9539 Applications

* and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc. The PCA9539; PCA9539R consists of two 8-bit configuration (input or output selec
