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

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

• Power Down Protection Provided on Inputs

• Balanced Propagation Delays

• Pin and Function Compatible with Other Standard Logic Families

• Chip Complexity: FETs = 56; Equivalent Gates = 14
