M74HCT27C1R

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 bufferedoutput, which gives highnoise immunity

and a stable output. All inputs areequipped with pro-

tectioncircuits 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.
