MC74HC03A/D

MC74HC03A

Quad 2-Input NAND Gate

with Open-Drain Outputs

High−Performance Silicon−Gate CMOS

The MC74HC03A is identical in pinout to the LS03. The device

inputs are compatible with Standard CMOS outputs; with pullup

resistors, they are compatible with LSTTL outputs.

The HC03A NAND gate has, as its outputs, a high−performance

MOS N−Channel transistor. This NAND gate can, therefore, with a

suitable pullup resistor, be used in wired−AND applications. Having

the output characteristic curves given in this data sheet, this device can

be used as an LED driver or in any other application that only requires

a sinking current.
