KK74AC244 Datasheet | Kodenshi AUK Group

TECHNICAL DATA .. Octal 3-State Noninverting Buffer/Line Driver/Line Receiver High-Speed Silicon-Gate CMOS The KK74AC244 is identical in pinout to the LS/ALS244, HC/HCT244. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible 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 m A ORDERING INFORMATION KK74AC244N Plastic KK74AC244DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Enable A, Enable B PIN 20=VCC PIN 10 = GND L L H X=don’t care Z = high impedance A,B L H X Outputs YA,YB L H Z ..
