GPIO Expander ICs - BU1850MUV

GPIO expander is useful especially for the application that is in short of IO ports. It can 1. Control GPIO output states by I2C write protocol. 2. Know GPIO input states by I2C 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.
