SL74HCT244

SL74HCT244 Octal 3-State Noninverting Buffer/Line Driver/Line Receiver High-Performance Silicon-Gate CMOS The SL74HCT244 is identical in pinout to the LS/ALS244. The device may be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs. The SL74HCT244 is an octal noninverting buffer/line driver/line receiver designed to be used with 3-state memory address drivers, clock drivers, and other bus-oriented systems. The device has non-inverted 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 SL74HCT244N Plastic SL74HCT244D 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 X=don’t care Z = high impedance A,B L H X Outputs YA,YB L H Z SLS System Logic Semiconductor SL74HCT244 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 2...
