Description: Low-voltage 16-bit I2C and SMBus I/O expander

Features

* I²C-bus to parallel port expander
* Operating power supply voltage range of 1.65 V to 5.5 V
* Low standby current consumption:
* 2.5 µA (maximum)
* Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inp

Applications

* It is designed for a wide voltage range of 1.65 V to 5.5 V with interrupt and default pull-up resistors on GPIOs. 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 bu
