No Preview Available ! SL74HCT240 Octal 3-State Inverting Buffer/Line Driver/Line Receiver High-Performance Silicon-Gate CMOS The SL74HCT240 is identical in pinout to the LS/ALS240. The SL74HCT240 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 bus- oriented 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 SL74HCT240N Plastic SL74HCT240D SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 20=VCC PIN 10 = GND FUNCTION TABLE Inputs Enable A, Enable B A,B LL LH HX X = don’t care Z = high impedance Outputs YA,YB H L Z SLS System Logic Semiconductor 1 page SL74HCT240 Figure 3.
