74VHC08
Quad 2-Input AND Gate
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 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 cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
