74VHC27 Triple 3-Input NOR Gate
July 1994
Revised April 1999
74VHC27
Triple 3-Input NOR Gate
General Description
The VHC27 is an advanced high speed CMOS 3-Input
NOR 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 3 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.
