s HIGH NOISE IMMUNITY :
VH = 0.7V (TYP) at Vcc = 4.5V
s BALANCED PROPAGATION DELAYS:
tPLH ≅ tPHL
s SYMMETRICAL OUTPUT IMPEDANCE:
|IOH| = IOL = 4mA (MIN)
s PIN AND FUNCTION COMPATIBLE WITH

DESCRIPTION
The M74HCT14 is an high speed CMOS HEX
SCHMITT INVERTER fabricated with silicon gate
C2MOS 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
HSC2MOS systems with TTL and NMOS
components.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
