DESCRIPTION
The M54/74HC27 is a high speed CMOS TRIPLE
3-INPUT NOR GATE fabricated in silicon gate
C2MOS technology.
It has the same high speed performance of LSTTL
combined with true CMOSlow power consumption.
The internal circuitis composedof 3stages includingbufferedoutput,whichgiveshighnoiseimmunity
anda stableoutput.Allinputsareequippedwith protectioncircuitsagainststaticdischarge andtransient
excess voltage.
