DESCRIPTION
The M54/74HCT02 is a high speed CMOS QUAD
2-INPUT NOR GATE fabricated in silicon gate
C2MOStechnology.It hasthesamehighspeedperformance of LSTTL combined with true CMOS low
power consumption. The internal circuit is composed of 3 stages including buffer output, which
giveshigh noise immunity andstable output. All inputs are equipped with protection circuits against
staticdischarge and transient excess voltage.
This integrated circuit has input and output characteristicsthat are fully compatible with 54/74LSTTL
logic families. M54/74HCT devices are designed to
directly interface HSC2MOSsystems with TTL and
NMOS components. They are also plugin replacements for LSTTL devices giving a reduction of
powerconsumption.
