TECHNICAL DATA KK74HC154A 1-of-16 Decoder/Demultiplexer High-Performance Silicon-Gate CMOS The KK74HC154A is identical in pinout to the LS/ALS154. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device, when enabled, selects one of 16 active-low outputs. Two active-low Chip Selects are provided to facilitate the chip-select, demultiplexing, and cascading functions. When either Chip Select is high, all outputs are high. The demultiplexing function is accomplished by using the Address inputs to select the desired device output. The KK74HC154A is primarily used for memory address decoding and data routing applications. • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1.0 µA • High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION KK74HC154AN Plastic KK74HC154ADW SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 24 =VCC PIN 12 = GND 1 KK74HC154A 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 KK74HC154A DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol Parameter Test Conditions V Guaranteed Limit 2 5 °C to -55°C 1.5 3.15 4.2 0.3 0.9 1.2 1.9 4.4 5.9 3.98 5.48 0.1 0.1 0.1 0.26 0.26 ±0.1 8.0 ≤85 °C 1.5 3.15 4.2 0.3 0.9 1.2 1.9 4.4 5.9 3.84 5.34 0.1 0.1 0.1 0.33 0.33 ±1.0 80 ≤125 °C 1.5 3.15 4.2 0.3 0.9 1.2 1.9 4.4 5.9 3.7 5.2 0.1 0.1 0.1 0.4 0.4 ±1.0 160 µA µA 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 µA VOUT=0.1 V or VCC-0.1 V ⎢IOUT⎢ ≤ 20 µA VIN=VIH or VIL ⎢IOUT⎢ ≤ 20 µA 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 µA 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=0µA 3 KK74HC154A AC ELECTRICAL CHARACTERISTICS (CL=50pF,Input tr=tf=6.0 ns) VCC Symbol tPLH, tPHL Parameter Maximum Propagation Delay, Input A to Output Y (Figures 1and 3) Maximum Propagation Delay , CS to Output Y (Figures 2 and 3) Maximum Output Transition Time, Any Output (Figures 2 and 3) Maximum Input Capacitance Power Dissipation Capacitance (Per Package) CPD Used to determine the no-load dynamic power consumption: PD=CPDVCC2f+ICCVCC V 2.0 4.5 6.0 2.0 4.5 6.0 2.0 4.5 6.0 Guaranteed Limit 25 °C to -55°C 190 38 32 175 35 30 75 15 13 10 ≤85°C 240 48 41 220 44 37 95 19 16 10 ≤125°C 285 57 48 265 53 45 110 22 19 10 Unit ns tPLH, tPHL ns tTLH, tTHL ns CIN pF Typical @25°C,VCC=5.0 V 80 pF FUNCTION TABLE Inputs L L L L L L L L L L L L L L L L L H L L L L L L L L L L L L L L L L H L L L L L L L L L H H H H H H H H X X L L L L H H H H L L L L H H H H X X L L H H L L H H L L H H L L H H X X X L H L H L H L H L H L H L H L H X X X L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H Outputs H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H H H H H L H H H CS1 CS2 A3 A2 A1 A0 Y0 Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y8 Y9 Y10 Y11 Y12 Y13 Y14 Y15 HHXX X = Don’t Care 4 KK74HC154A Figure 1.
