M74HCT32 General Description


The M54/74HCT32 is a high speed CMOS 2-INPUT OR GATE fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. It achieves the high speed operation similar to equivalent LSTTL while maintaining theCMOS 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 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 systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption.
