Features

* 8-bit I2C GPIO
* 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 stand-by current
* Noise filter on SCL/SDA inputs

Applications

* and was developed to enhance the Philips family of I2C I/O expanders. The improvements include higher drive capability, 5V I/O tolerance, lower supply current, individual I/O configuration, 400 kHz clock frequency, and smaller packaging. I/O expanders provide a simple solution when additional I/O is
