74VHC08 #74VHCT08

Quad 2-Input AND Gate

General Description

The 74VHC/VHCT08 is an advanced high speed CMOS 2

Input AND Gate fabricated with silicon gate CMOS technol-

ogy. It achieves the high-speed operation similar to equiva-

lent Bipolar Schottky TTL while maintaining the CMOS low

power dissipation.

The internal circuit is composed of 4 stages including buffer

output, which provide high noise immunity and stable out-

put. An input protection circuit insures that 0V to 7V can be

applied to the input pins without regard to the supply volt-

age. This device can be used to interface 5V to 3V systems

and two supply systems such as battery backup. This circuit

prevents device destruction due to mismatched supply and

input voltages.

Absolute Maximum Ratings are values beyond

which the device may be damaged or have its useful life

impaired. The databook specifications should be met, with-
