| TECHNICAL DATA KK74HC158A Quad 2-Input Data Selectors/Multiplexers High-Performance Silicon-Gate CMOS The KK74HC158A is identical in pinout to the LS/ALS158. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL 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 A * High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION KK74HC158AN Plastic KK74HC158AD SOIC TA = -55 to 125 C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs PIN 16 =VCC PIN 8 = GND Output Enable H L L Select X L H Outputs Y0-Y3 H A0-A3 B0-B3 X=don't care A0-A3,B0-B3=the levels of the respective Data-Word Inputs 1 KK74HC158A 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 25 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 KK74HC158A DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol Parameter Test Conditions V Guaranteed Limit 25 C to -55C 1.5 3.15 4.2 0.5 1.35 1.8 1.9 4.4 5.9 3.98 5.48 0.1 0.1 0.1 0.26 0.26 0.1 4.0 85 C 1.5 3.15 4.2 0.5 1.35 1.8 1.9 4.4 5.9 3.84 5.34 0.1 0.1 0.1 0.33 0.33 1.0 40 125 C 1.5 3.15 4.2 0.5 1.35 1.8 1.9 4.4 5.9 3.7 5.2 0.1 0.1 0.1 0.4 0.4 1.0 160 A A V Unit VIH Minimum HighLevel Input Voltage Maximum Low Level Input Voltage Minimum HighLevel Output Voltage VOUT=0.1 V or VCC-0.1 V IOUT 20 A VOUT=0.1 V or VCC-0.1 V IOUT 20 A VIN=VIH or VIL IOUT 20 A VIN=VIH or VIL IOUT 4.0 mA IOUT 5.2 mA 2.0 4.5 6.0 2.0 4.5 6.0 2.0 4.5 6.0 4.5 6.0 2.0 4.5 6.0 4.5 6.0 6.0 6.0 V VIL V VOH V VOL Maximum LowLevel Output Voltage VIN=VIH or VIL IOUT 20 A VIN=VIH or VIL IOUT 4.0 mA IOUT 5.2 mA IIN ICC Maximum Input Leakage Current Maximum Quiescent Supply Current (per Package) VIN=VCC or GND VIN=VCC or GND IOUT=0A 3 KK74HC158A AC ELECTRICAL CHARACTERISTICS (CL=50pF,Input tr=tf=6.0 ns) VCC Symbol Parameter V Guaranteed Limit 25 C to -55C 105 21 18 110 22 19 100 20 17 75 15 13 10 85C 125C Unit tPLH, tPHL Maximum Propagation Delay, Input A or B to Output Y (Figures 1and 4) Maximum Propagation Delay , Select to Output Y (Figures 2 and 4) Maximum Propagation Delay , Output Enable to Output Y (Figures 3 and 4) Maximum Output Transition Time, Any Output (Figures 1 and 4) Maximum Input Capacitance Power Dissipation Capacitance (Per Package) 2.0 4.5 6.0 2.0 4.5 6.0 2.0 4.5 6.0 2.0 4.5 6.0 - 130 26 22 140 28 24 125 25 21 95 19 16 10 160 32 27 165 33 28 150 30 26 110 22 19 10 ns tPLH, tPHL ns tPLH, tPHL ns tTLH, tTHL ns CIN pF Typical @25C,VCC=5.0 V 33 pF CPD Used to determine the no-load dynamic power consumption: PD=CPDVCC2f+ICCVCC Figure 1.
