PIN AND FUNCTION COMPATIBLE WITH

54/74LS14

The M54/74HC14 is a high speed CMOS HEX

SCHMITT INVERTER fabricated in silicon gate

C

2MOS technology. It has the same high speed 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 % VCC hysteresis level.

This together with its schmitt trigger function allows

it to be used on line receivers with slow rise/fall input

signals. All inputs are equipped with protection cir-

cuits against static discharge and transient excess

voltage.
