54LS14/DM74LS14 Hex Inverters
with Schmitt Trigger Inputs

General Description

This device contains six independent gates each of which
performs the logic INVERT function. Each input has hyster-
esis which increases the noise immunity and transforms a
slowly changing input signal to a fast changing, jitter free
output.
