Description: low voltage GPIO

Features

* 400 kHz I2C-bus serial interface NXP Semiconductors PCA9574 8-bit I2C-bus and SMBus, level translating, low voltage GPIO with reset and interrupt
* Compliant with I2C-bus Standard-mode (100 kHz)
* Separate supply rails for core logic and I/O bank provides voltage level

Applications

* and was developed to enhance the NXP family of I2C-bus I/O expanders. The improvements include lower supply current, lower operating voltage of 1.1 V to 3.6 V, dual and separate supply rails to allow voltage level translation anywhere between 1.1 V and 3.6 V, 400 kHz clock frequency, and smaller pac
