No Preview Available ! TECHNICAL DATA Octal 3-State Noninverting Buffer/Line Driver/Line Receiver High-Performance Silicon-Gate CMOS KK74HC244A The KK74HC244A is identical in pinout to the LS/ALS244. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL 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 • High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION KK74HC244AN Plastic KK74HC244ADW SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 20=VCC PIN 10 = GND www.DataSheet4U.net FUNCTION TABLE Inputs Enable A, Enable B A,B LL LH HX X=don’t care Z = high impedance Outputs YA,YB L H Z 1 1 page KK74HC244A EXPANDED LOGIC DIAGRAM (1/8 of the Device) 5 5 Page
