DESCRIPTION
The M74HCT14 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 M74HCT04 but all inputs have 0.7 V hysteresis level. This together with its schmitt trigger function allows it to be used on line receiver with slow rise/fall input signals.
