General Description
The NC7S14 is a sing le high perfo rmance CMOS Inverter
with Schmitt Trigger input. The circuit desig n provide s hysteresis between the positive-going and negative going
input thresholds thereby improving noise margins.
Advanced Silicon Gate CMOS fabrication assures high
speed and low pow er circuit operation over a broad V
range. ESD protecti on diodes inherently guard both input
and output with respect to the V

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power
