SL74HC240

SL74HC240 Octal 3-State Inverting Buffer/Line Driver/Line Receiver High-Performance Silicon-Gate CMOS The SL74HC240 is identical in pinout to the LS/ALS240. 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 High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION SL74HC240N Plastic SL74HC240D SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Enable A, Enable B PIN 20=VCC PIN 10 = GND L L H A,B L H X Outputs YA,YB H L Z X = don’t care Z = high impedance SLS System Logic Semiconductor SL74HC240 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...
