NOTE:

This device contains protective circuitry to guard against damage due to high static voltage or electrical

fields. However, normal precautions are advised to avoid application of any voltages higher than maximum

rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied

to an appropriate logic voltage level (e.g., either GND or VCC).
