DESCRIPTION

The M54/74HCT02 is a high speed CMOS QUAD

2-INPUT NOR GATE fabricated in silicon gate

C2MOS technology. It has the same high speed per-

formance of LSTTL combined with true CMOS low

power consumption. The internal circuit is com-

posed of 3 stages including buffer output, which

gives high noise immunity and stable output. All in-

puts are equipped with protection circuits against

static discharge and transient excess voltage.

This integrated circuit has input and output charac-

teristics that are fully compatible with 54/74 LSTTL

logic families. M54/74HCT devices are designed to

directly interface HSC2MOS systems with TTL and

NMOS components. They are also plug in replace-

ments for LSTTL devices giving a reduction of

power consumption.
