Description:

Low-voltage 16-bit I2C and SMBus low-power I/O expander

Features

* I²C-bus to parallel port expander
* Operating power supply voltage range of 2.3 V to 5.5 V
* Ultra low standby current consumption:
* 1 µA (maximum)
* Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA

Applications

* It is designed for a wide voltage range of 2.3 V to 5.5 V with interrupt. Nexperia GPIO expanders provide an elegant solution when additional IOs are needed while keeping the interconnections to a minimum, for example, in ACPI power switches, sensors, push buttons, LEDs and fan control.
