DESCRIPTION

The M54/74HCT32 is a high speed CMOS 2-INPUT

OR GATE fabricated in silicon gate C2MOS technol-

ogy. It has the same high speed performance of

LSTTL combined with true CMOS low power con-

sumption. It achieves the high speed operation similar

to equivalent LSTTL while maintaining the CMOS low

power dissipation. The internal circuit is composed of

2 stages including buffered output, which gives high

noise immunity and a stable output. All inputs are

equipped with protection circuits against static dis-

charge 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.
