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.
The M74HCT14 is designed to directly interface
HSC
2
MOS systems with TTL and NMOS
components.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
