DESCRIPTION
The M74HCT14 is an high speed CMOS HEX
SCHMI TT IN VE RTER fabr icat ed with s ilicon ga te
2
C
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
2
HSC
MOS systems with TTL and NMOS
components.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (R ef er to Test Circuit). Aver age opera ting current can be obta i ned by the following equa tion. I
-40 to 85°C -55 to 125°C
= CPD x VCC x fIN + ICC
