General Description

The VHC08 is an advanced high speed CMOS 2 Input AND Gate

fabricated with silicon gate CMOS technology. It achieves the

high?speed operation similar to equivalent 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 output. An input

protection circuit insures that 0 V to 7 V can be applied to the input

pins without regard to the supply voltage. This device can be used to

interface 5 V to 3 V systems and two supply systems such as battery

backup. This circuit prevents device destruction due to mismatched

supply and input voltages.
