DESCRIPTION
The M54/74HCT14 is a high speed CMOS HEX
SCHMITT INVERTER fabricated in silicon gate
C2MOStechnology. Ithasthesamehighspeedperformance of LSTTL combined with trueCMOS low
power consumption. Pinconfiguration and function
are the same as those of the HCT04but all inputs
have 0.7 V hysteresis level.This together with its
schmitt trigger functionallows it to be used on line
receivers with slow rise/fall inputsignals. Thisintegrated circuit has input and output characteristics
that are fully compatible with 54/74 LSTTL logic
families. M54/74HCT devices are designed to directly interface HSC2MOS systems with TTL and
NMOS components. They are also plugin replacements for LSTTL devices giving a reduction of
power consumption.All inputs areequipped with pro-
