M74HC14 General Description

The M54/74HC14 is a high speed CMOS HEX SCHMITT INVERTER fabricated in silicon gate C2MOStechnology. It has the same highspeed performance 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_CC 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 circuits against static discharge and transient excess voltage.
