09098EAT02 ●Description GPIO expander is useful especially for the application that is in short of IO ports.
It can 2 1.
Control GPIO output states by I C write protocol.
2 2.
Know GPIO input states by I C read protocol.
Furthermore,it has the interrupt function that can release CPU from polling the registers in the GPIO expander.
GPIO expander are also equipped with Built-in power on reset, 3V tolerant input,and NMOS open-drain output.
●Features 1) An 8-Port General purpose input/output interface 150kΩPull-down resistance.
2) NMOS Open-drain output interrupt controller with up to 1us pulse noise filter and bit mask function for individual GPIO port.
3) 3volt tolerant Input 4) Built-in Power On Reset 5) 3mmx3mm small package ●Absolute maximum ratings o (Ta=25 C) Parameter Supply Voltage*1 Symbol VDD VDDIO VI Input voltage VIT Storage temperature range Package power This IC is not designed to be X-ray proof.
