TECHNICAL DATA IN74AC153 Dual 4-Input Data Selector/Multiplexer High-Speed Silicon-Gate CMOS The IN74AC153 is identical in pinout to the LS/ALS153, HC/HCT153. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. The Address Inputs select one of four Data Inputs from each multiplexer. Each multiplexer has an active-low Strobe control and a noninverting output. • 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 • Output Source/Sink 24 mA ORDERING INFORMATION IN74AC153N Plastic IN74AC153D SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs PIN 16 =VCC PIN 8 = GND Output A1 A0 Strobe Y X X H L L L L D0 L H L D1 H L L D2 H H L D3 D0,D1...D3=the level of the respective Data Input X = don’t care 183 IN74AC153 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. 184 IN74AC153 DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) VCC Guaranteed Limits V 25 °C -40°C to 85°C Unit 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 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 Minimum High-Level 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 Symbol Parameter VIH Minimum High-Level Input Voltage VIL VOH Test Conditions * VIN=VIH or VIL IOH=-12 mA IOH=-24 mA IOH=-24 mA VOL Maximum Low-Level 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.
