DESCRIPTIONThe M54HC14is an high speed CMOS HEX
SCHMITT INVERTER fabricated with silicon gate2 MOS technology. Pin configuration and
function are the sameas thoseof the M54HC04
butall inputs have 20% VCC hysteresis level.
This, together with its schmitt trigger function,
allowsitto 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.

ELECTRICAL CHARACTERISTICS(CL=50 pF, Inputtr=tf =6ns)
CAPACITIVE CHARACTERISTICS CPD isdefinedasthe valueofthe IC’s internal equivalent capacitance whichis calculatedfrom theoperating current consumption without
load. (Referto TestCircuit). Average operating currentcanbe obtainedbythe following equation. ICC(opr) =CPDxVCC xfIN +ICC/6(per gate)
TEST CIRCUIT= 50pFor equivalent (includesjig and probe capacitance) =ZOUTof pulse generator (typically 50Ω)
