MC74VHCT02A
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 3.3 V to 5.0 V, because it
has full 5 V CMOS level output swings.
The VHCT02A input structures provide protection when voltages
between 0 V and 5.5 V are applied, regardless of the supply voltage.

The output structures also provide protection when V = 0 V. These

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 7 V, allowing the interface of 5 V systems
to 3 V systems.
