DESCRIPTION
The M54/74HCT27 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 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. This integrated circuit has input and
output characteristics that are fully compatible with
54/74 LSTTL logic families. M54/74HCT devices
are designed to directly interface HSC2MOS sys-
tems with TTL and NMOS components. They are
also plug in replacements for LSTTL devices giving
a reduction of power consumption.
