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.
