TECHNICAL DATA KK74AC158 Quad 2-Input Data Selector/Multiplexer High-Speed Silicon-Gate CMOS The KK74AC158 is identical in pinout to the LS/ALS158, HC/HCT158. 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 invertered form. A high level on the Output Enable input sets all four Y outputs to a high 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 KK74AC158N Plastic KK74AC158D SOIC TA = -40° to 85° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs PIN 16 =VCC PIN 8 = GND Outputs Output Enable Select Y0-Y3 H X H L L A0-A3 L H B0-B3 X=don’t care A0-A3,B0-B3=the levels of the respective Data-Word Inputs 1 KK74AC158 MAXIMUM RATINGS* Symbol Parameter Value Unit -0.5 to +7.0 V VCC DC Supply Voltage (Referenced to GND) VIN DC Input Voltage (Referenced to GND) -0.5 to VCC +0.5 V DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V DC Input Current, per Pin ±20 mA IOUT DC Output Sink/Source Current, per Pin ±50 mA ICC DC Supply Current, VCC and GND Pins ±50 mA PD Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ 750 500 mW -65 to +150 °C 260 °C VOUT IIN Tstg TL Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) * 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 KK74AC158 DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol Parameter Test Conditions Guaranteed Limits V 25 °C -40°C to 85°C Unit VIH Minimum HighLevel Input Voltage VOUT=0.1 V or VCC-0.1 V 3.0 4.5 5.5 2.1 3.15 3.85 2.1 3.15 3.85 V VIL Maximum Low Level Input Voltage VOUT=0.1 V or VCC-0.1 V 3.0 4.5 5.5 0.9 1.35 1.65 0.9 1.35 1.65 V VOH Minimum HighLevel Output Voltage IOUT ≤ -50 µA 3.0 4.5 5.5 2.9 4.4 5.4 2.9 4.4 5.4 V 3.0 4.5 5.5 2.56 3.86 4.86 2.46 3.76 4.76 3.0 4.5 5.5 0.1 0.1 0.1 0.1 0.1 0.1 VIN=VIH or VIL IOL=12 mA IOL=24 mA IOL=24 mA 3.0 4.5 5.5 0.36 0.36 0.36 0.44 0.44 0.44 Maximum Input Leakage Current VIN=VCC or GND 5.5 ±0.1 ±1.0 µA IOLD +Minimum Dynamic Output Current VOLD=1.65 V Max 5.5 75 mA IOHD +Minimum Dynamic Output Current VOHD=3.85 V Min 5.5 -75 mA ICC Maximum Quiescent Supply Current (per Package) VIN=VCC or GND 5.5 80 µA * VIN=VIH or VIL IOH=-12 mA IOH=-24 mA IOH=-24 mA VOL Maximum LowLevel Output Voltage IOUT ≤ 50 µA V * IIN 8.0 * All outputs loaded; thresholds on input associated with output under test. +Maximum test duration 2.0 ms, one output loaded at a time.
