Functional Description

• Quad 2-Input NAND Gate

General

The 74VHCT00AFT is an advanced high speed CMOS 2-INPUT NAND 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 input voltage are compatible with TTL output voltage.

This device may be used as a level converter for interfacing 3.3 V to 5 V system.

Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins

without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and

input/output voltages such as battery back up, hot board insertion, etc.

Note: VCC = 0 V

Features
