Description
TECHNICAL DATA
Triple 3-Input NOR Gate
High-Speed Silicon-Gate CMOS
The IN74AC27 is identical in pinout to the LS/ALS27, HC/HCT27. 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
