PIN AND FUNCTION COMPATIBLE WITH

DESCRIPTION
The M74HC14 is an high speed CMOS HEX
SCHMITT INVERTER fabricated with silicon gate
C
2
MOS technology. Pin configuration and
function are the same as those of the M74HC04
but all inputs have 20% V
cc
hysteresis level.
This, together with its schmitt trigger function,
allows it to be used on line receivers with slow
rise/fall input signals.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
