TECHNICAL DATA Dual 4-Input AND Gate High-Speed Silicon-Gate CMOS The IN74AC21 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/
