Octal 3-State Noninverting
Buffer/Line Driver/Line Receiver
High-Speed Silicon-Gate CMOS
KK74AC244
The KK74AC244 is identical in pinout to the LS/ALS244,
HC/HCT244. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LS/ALS outputs.
This octal noninverting buffer/line driver/line receiver is designed to
be used with 3-state memory address drivers, clock drivers, and other
bus-oriented systems. The device has noninverting outputs and two
active-low output enables.
• 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
