IO Expander

I2C to GPIO expander and I2C Switch for I2C-bus applications. The power supplier voltage range is from 1.65 V to 5.5 V for GPIO expander and 2.5V to 5.5V for I2C Switch. The open-drain interrupt (INT) output is used to indicate the system master that an input state has changed. The power-on reset sets the registers to their default values and initializes the device state machine. Three hardware pins (A0, A1, A2) select the fixed I2C-bus address and allow up to eight devices to share the same I2C-bus.
