The M54/74HC27 is a high speed CMOS TRIPLE
3-INPUT NOR GATE fabricated in silicon gate
C
2MOS technology.
It has the same high speed performance of LSTTL
combined with true CMOS low power consumption.
The internal circuit is composed of 3 stages includ-
ing buffered output, which gives high noise immunity
and a stable output. All inputs are equipped with pro-
tection circuits against static discharge and transient
excess voltage.
