KK74AC241N

TECHNICAL DATA KK74AC241 Octal 3-State Noninverting Buffer/Line Driver/Line Receiver High-Speed Silicon-Gate CMOS The KK74AC241 is identical in pinout to the LS/ALS241, HC/HCT241. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. 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. • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1.0 µA; 0.1 µA @ 25°C • High Noise Immunity Characteristic of CMOS Devices • Outputs Source/Sink 24 mA ORDERING INFORMATION KK74AC241N Plastic KK74AC241DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Enable A L PIN 20=VCC PIN 10 = GND 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 1 KK74AC241 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 Sink/Source 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 -0.5 to VCC +0.5 -0.5 to VCC +0.5 ±20 ±50 ±50 750 500 -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. 2 KK74AC241 DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol VIH Parameter Minimum HighLevel Input Voltage Maximum Low Level Input Voltage Minimum HighLevel Output Voltage Test Conditions VOUT= VCC-0.1 V V 3.0 4.5 5.5 3.0 4.5 5.5 3.0 4.5 5.5 3.0 4.5 5.5 3.0 4.5 5.5 3.0 4.5 5.5 5.5 5.5 Guaranteed Limits 2 5 °C 2.1 3.15 3.85 0.9 1.35 1.65 2.9 4.4 5.4 2.56 3.86 4.86 0.1 0.1 0.1 0.36 0.36 0.36 ±0.1 ±0.5 -40°C to 8 5 °C 2.1 3.15 3.85 0.9 1.35 1.65 2.9 4.4 5.4 2.46 3.76 4.76 0.1 0.1 0.1 0.44 0.44 0.44 ±1.0 ±5.0 µA µA V Unit V VIL VOUT= 0.1 V V VOH IOUT ≤ -50 µA V VIN= VIH IOH=-12 mA IOH=-24 mA IOH=-24 mA VOL Maximum LowLevel Output Voltage IOUT ≤ 50 µA * * VIN=VIL IOL=12 mA IOL=24 mA IOL=24 mA VIN=VCC or GND IIN IOZ Maximum Input Leakage Current Maximum ThreeState Leakage Current +Minimum Dynamic Output Current +Minimum Dynamic Output Current Maximum Quiescent Supply Current (per Package) VIN (OE)= VIH or VIL VIN =VCC or GND VOUT =VCC or GND VOLD=1.65 V Max VOHD=3.85 V Min VIN=VCC or GND IOLD IOHD ICC 5.5 5.5 5.5 8.0 75 -75 80 mA mA µA * All outputs loaded; thresholds on input associated with output under test. +Maximum test duration 2.0 ms, one output loaded at a time.
