The recommended operating voltage range for the TCA6408ARSVR is 1.65V to 5.5V.
The TCA6408ARSVR can be configured for I2C or SMBus interface by connecting the SCL pin to a pull-up resistor and the SDA pin to a pull-up resistor or an open-drain output.
The maximum frequency of the clock signal that can be used with the TCA6408ARSVR is 400 kHz for I2C mode and 100 kHz for SMBus mode.
The TCA6408ARSVR can be reset by pulling the RESET pin low for a minimum of 1.5 ms.
The INT pin on the TCA6408ARSVR is an active-low interrupt output that indicates when an input pin has changed state.
