KK74AC240

TECHNICAL DATA www.DataSheet4U.com KK74AC240 Octal 3-State Inverting Buffer/Line Driver/Line Receiver High-Speed Silicon-Gate CMOS The KK74AC240 is identical in pinout to the LS/ALS240, HC/HCT240. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This octal inverting buffer/line driver/line receiver is designed to be used with 3-state memory address drivers, clock drivers, and other busoriented systems. The device has inverting 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 ORDERING INFORMATION KK74AC240N Plastic KK74AC240DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Enable A, Enable B L L PIN 20=VCC PIN 10 = GND H A,B L H X Outputs YA,YB H L Z X = don’t care Z = high impedance 1 www.DataSheet4U.com KK74AC240 MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Sink/Source Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or ...
