MC74VHC1G02

2-Input NOR Gate

The MC74VHC1G02 is an advanced high speed CMOS 2–input

NOR gate fabricated with silicon gate CMOS technology. It achieves

high speed operation similar to equivalent Bipolar Schottky TTL

while maintaining CMOS low power dissipation.

The internal circuit is composed of three stages, including a buffer

output which provides high noise immunity and stable output.

The MC74VHC1G02 input structure provides protection when

voltages up to 7V are applied, regardless of the supply voltage. This

allows the MC74VHC1G02 to be used to interface 5V circuits to 3V

circuits.
