DESCRIPTION
The M54/74HC14 is a high speed CMOS HEX
SCHMITT INVERTER fabricated in silicon gate
C2MOStechnology.Ithasthesame highspeedperformance of LSTTL combined with true CMOS low
power consumption. Pin configuration and function
are the same as those of the HC04 but all inputs
have20 % VCChysteresislevel.
This together with its schmitt trigger functionallows
it to beused on linereceiverswith slowrise/fallinput
signals. All inputs are equipped with protection circuits against static discharge and transient excess
voltage.
