KK74HC03A

KK74HC03A

Quad 2-Input NAND Gate

with Open-Drain Outputs

High-Performance Silicon-Gate CMOS

ORDERING INFORMATION

KK74HC03AN Plastic

KK74HC03AD SOIC

The KK74HC03A is identical in pinout to the LS/ALS03. The device

inputs are compatible with standard CMOS outputs; with pullup resistors,

they are compatible with LS/ALSTTL outputs.

The KK74HC03A NAND gate has, as its output, a high-performance

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

suitable pullup resistor, be used in wired-AND applications.

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 µA

• High Noise Immunity Characteristic of CMOS Devices
