The M54/74HC20 is a highspeed CMOS DUAL 4-
INPUT NAND GATE fabricated in silicon gate
C
2
MOStechnology.Ithas thesame highspeedper-
formance of LSTTL combined with true CMOS low
powerconsumption.
The internal circuit is composed of 3 stages includ-
ingbufferedoutput,which giveshighnoiseimmunity
and astableoutput. Allinputsareequippedwithpro-
tectioncircuitsagainst staticdischarge and transient
excess voltage.
