DUAL 2-INPUT NOR GATE
The TC7WH02 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
ensures that 0 to 7V can be applied to the input pins
without regard to the supply voltage. This device can be
used to interface 5V to 3V systems and two supply
systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input
voltages.
