DESCRIPTION

The M54/74HCT14 is a high speed CMOS HEX

SCHMITT INVERTER fabricated in silicon gate

C²MOS technology. It has the same highspeed per-

formance of LSTTL combined with true CMOS low

power consumption. Pin configuration and function

are the same as those of the HCT04 but all inputs

have 0.7 V hysteresis level.This together with its

schmitt trigger function allows it to be used on line

receivers with slow rise/fall input signals. This inte-

grated circuit has input and output characteristics

that are fully compatible with 54/74 LSTTL logic

families. M54/74HCT devices are designed to di-

rectly interface HSC²MOS systems with TTL and

NMOS components. They are also plug in replace-

ments for LSTTL devices giving a reduction of

power consumption.All inputs are equipped with pro-

PIN CONNECTIONS (top view)
