IN74AC20

DUAL 4-INPUT NAND GATE

High-Speed Silicon-Gate CMOS

The IN74AC20 is identical in pinout to the LS/ALS20,

HC/HCT20. The device inputs are compatible with

standard CMOS outputs; with pullup resistors, they are

compatible with LS/ALS outputs.

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 µA; 0.1 µA @ 25°C

• High Noise Immunity Characteristic of CMOS Devices

• Outputs Source/Sink 24 mA
