Description
The M74HC14 is a high speed CMOS hex
Schmitt inverter fabricated with silicon gate
2
C MOS technology. Pin configuration and
functions are the same as those of the M74HC04
but all the inputs have 20% V hysteresis level.
CC
This, together with its Schmitt trigger function,
allows the device 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.

Maximum rating
Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only, and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.

1. CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current
consumption without load. (Refer to test circuit). Average operating current can be obtained by the following equation:
I
CC(opr) = CPD x VCC x fIN + ICC/6(per gate).
