Functional Description
• Quad 2-Input NOR Gate

General
The 74VHC02FT is an advanced high speed CMOS 2-INPUT NOR GATE fabricated with silicon gate C2MOS
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 5.5 V can be applied to the input pins without regard to the supply
voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched supply and input voltages.
