DESCRIPTION
The M74HC14 is an high speed CMOS HEX
SCHMI TT IN VE RTER fabr icat ed with s ilicon ga te
2
MOS technology. Pin configuration and
C
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.
