KK74HCT240A

TECHNICAL DATA KK74HCT240A Octal 3-State Inverting Buffer/Line Driver/Line Receiver High-Performance Silicon-Gate CMOS The KK74HCT240A is identical in pinout to the LS/ALS240. The KK74HCT240A may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. 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. TTL/NMOS Compatible Input Levels Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 4.5 to 5.5 V Low Input Current: 1.0 µA ORDERING INFORMATION KK74HCT240AN P lastic KK74HCT240ADW SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Enable A, Enable B L L H A,B L H X Outputs YA,YB H L Z PIN 20=VCC PIN 10 = GND X = don’t care Z = high impedance www.DataSheet4U.net 1 KK74HCT240A 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 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 SOIC Package) Value -0.5 to +7.0 -1.5 to VCC +1.5 -0.5 to VCC +0.5 ±20 ±35 ±75 750 500 -65 to +150 26...
