CAUTION
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 voltage level.
