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
