SL74HC00 Quad 2-Input NAND Gate High-Performance Silicon-Gate CMOS The SL74HC00 is identical in pinout to the LS/ALS00. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. 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 ORDERING INFORMATION SL74HC00N Plastic SL74HC0.
