Quad 2-Input NOR Gate
The VHC02 is an advanced high-speed CMOS 2-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 output. An input protection circuit
insures that 0V to 7V can be applied to the input pins with-
out regard to the supply voltage. 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.
