DC Electrical Characteristics
This device contains circuitry protecting against damage from high-static voltage or
electrical fields. However, it is advised that precautions be taken to avoid application of any
voltages higher than the maximum-rated voltages to this high-impedance circuit. Reliability
of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (either
GND or V
