| SL74HCT241 Octal 3-State Noninverting Buffer/Line Driver/Line Receiver High-Performance Silicon-Gate CMOS The SL74HCT241 is identical in pinout to the LS/ALS241. The SL74HCT241 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. This octal noninverting 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 noninverting outputs and two output enables. Enable A is active-low and Enable B is active-high. * 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 A ORDERING INFORMATION SL74HCT241N Plastic SL74HCT241D SOIC TA = -55 to 125 C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Enable A PIN 20=VCC PIN 10 = GND L L H A L H X Output YA L H Z Inputs Enable B H H L B L H X Output YB L H Z X = don't care Z = high impedance SLS System Logic Semiconductor SL74HCT241 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 +150 260 Unit V V V mA mA mA mW C C Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND(VIN or VOUT)VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
