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.
