circuitry to guard against damage

due to high static voltages or electric

fields. However, precautions must

be taken to avoid applications of any

voltage higher than maximum rated

voltages to this high–impedance cir-

cuit. For proper operation, V in and

V out should be constrained to the

range GND

tied to an appropriate logic voltage

level (e.g., either GND or V CC ).

Unused outputs must be left open.
