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

The SL74HC03 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 SL74HC03 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
