DESCRIPTION

PIN CONNECTIONS (top view)

The M54/74HC14 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 HC04 but all inputs

have 20 % V_CChysteresis level.

This together with its schmitt trigger function allows

it to beused on line receivers with slow rise/fall input

signals. All inputs are equipped with protection cir-

cuits against static discharge and transient excess

voltage.
