Functional Description

• Quad 2-Input NAND Gate (Open Drain)

General

The 74VHC03FT 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.

Pin configuration and function are the same as the 74VHC00FT. But the 74VHC03FT has, as its outputs, high

performance MOS N-channel transistors. (OPEN-DRAIN outputs) This device can, therefore, with a suitable

pull-up resistors, be used in wired-AND, LED driver and other application.

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.
