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.
