Quad 2-Input NAND Gate
with Open-Drain Outputs
High-Performance Silicon-Gate CMOS

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
