Tristate Function (Pad 1):
Output (Pad 3) is active if Pad 1 is not connected or a
voltage of 2.2V or greater is applied to Pad 1. Output
is high impedance when a voltage of 0.8V or lower is
applied to Pad 1.
Note: Parameters are measured at ambient temperature of 25°C,
supply voltage as stated and a load of 15pF
