The PCA9539BSHP can support I2C bus frequencies up to 400 kHz.
The PCA9539BSHP can be configured to operate in 8-bit or 16-bit mode by setting the MODE pin high or low, respectively, during power-up or reset.
The PCA9539BSHP can sink or source up to 25 mA of current on each output pin.
The PCA9539BSHP can be reset by asserting the RESET pin low for at least 1 ms.
The INT pin is an active-low interrupt output that is asserted when a change is detected on any of the input pins.
