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
