DESCRIPTION
The M74HC14 is an high speed CMOS HEX
SCHMITT INVERTER fabricated with silicon gate
C MOS technology. Pin configuration and
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

function are the same as those of the M74HC04
but all inputs have 20% V hysteresis level.
cc
This, together with its schmitt trigger function,
allows it to be used on line receivers with slow
rise/fall input signals.
