KK74AC157

TECHNICAL DATA KK74AC157 Quad 2-Input Data Selector/Multiplexer High-Speed Silicon-Gate CMOS The KK74AC157 is identical in pinout to the LS/ALS157, HC/HCT157. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. This device routes 2 nibbles (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in noninvertered form. A high level on the Output Enable input sets all four Y outputs to a low level. • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1.0 µA; 0.1µA @ 25°C • High Noise Immunity Characteristic of CMOS Devices • Outputs Source/Sink 24 mA ORDERING INFORMATION KK74AC157N Plastic KK74AC157D SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs PIN 16 =VCC PIN 8 = GND Output Enable H L L Select X L H Outputs Y0-Y3 L A0-A3 B0-B3 X=don’t care A0-A3,B0-B3=the levels of the respective Data-Word Inputs 1 KK74AC157 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 KK74AC157 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=0.1 V or 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 5.5 5.5 8.0 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 -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 75 -75 80 µA mA mA µA V Unit V VIL VOUT=0.1 V or VCC-0.1 V V VOH IOUT ≤ -50 µA V VIN=VIH or VIL IOH=-12 mA IOH=-24 mA IOH=-24 mA VOL Maximum LowLevel Output Voltage IOUT ≤ 50 µA * * VIN=VIH or VIL IOL=12 mA IOL=24 mA IOL=24 mA VIN=VCC or GND VOLD=1.65 V Max VOHD=3.85 V Min VIN=VCC or GND IIN IOLD IOHD ICC Maximum Input Leakage Current +Minimum Dynamic Output Current +Minimum Dynamic Output Current Maximum Quiescent Supply Current (per Package) * All outputs loaded; thresholds on input associated with output under test. +Maximum test duration 2.0 ms, one output loaded at a time.
