PCA9555 - 16-bit I2C-bus and SMBus I/O port

PCA9555 Description

PCA9555 16-bit I2C-bus and SMBus I/O port with interrupt Rev.10 * 8 November 2017 Product data sheet 1.General .
The PCA9555 is a 24-pin CMOS device that provides 16 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and.

PCA9555 Features

* Operating power supply voltage range of 2.3 V to 5.5 V
* 5 V tolerant I/Os
* Polarity Inversion register
* Active LOW interrupt output
* Low standby current
* Noise filter on SCL/SDA inputs
* No glitch on power-up

PCA9555 Applications

* and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvements include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed f
