Quad 2−Input NOR Gate

The MC74VHCT02A is an advanced high speed CMOS 2−input

NOR gate fabricated with silicon gate CMOS technology. It achieves

high speed operation similar to equivalent Bipolar Schottky TTL

while maintaining CMOS low power dissipation.

The VHCT inputs are compatible with TTL levels. This device can

be used as a level converter for interfacing 3.3V to 5.0V, because it has

full 5V CMOS level output swings.

The VHCT02A input structures provide protection when voltages

between 0V and 5.5V are applied, regardless of the supply voltage.

input and output structures help prevent device destruction caused by

supply voltage − input/output voltage mismatch, battery backup, hot

insertion, etc.

The internal circuit is composed of three stages, including a buffer

output which provides high noise immunity and stable output. The

inputs tolerate voltages up to 7V, allowing the interface of 5V systems

to 3V systems.

apply to both standard and Pb−free devices. Please see our website at
