TECHNICAL DATA
Dual 4-Input AND Gate
High-Speed Silicon-Gate CMOS
KK74AC21
The KK74AC21 is identical in pinout to the LS/ALS21, HC/HCT21.
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
