The MC74VHCT08A is an advanced high speed CMOS 2−input

AND 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 5.0 V CMOS level output swings.

The VHCT08A 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 VCC = 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 7.0 V, allowing the interface of 5.0 V

systems to 3.0 V systems.
