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/Sink 24 mA
