TECHNICAL DATA KK74AC253 Dual 4-Input Data Selector/Multiplexer with 3-State Otputs High-Speed Silicon-Gate CMOS The KK74AC253 is identical in pinout to the LS/ALS253, HC/HCT253. 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 Output Enable control and a three-state 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 • Outputs Source/Sink 24 mA ORDERING INFORMATION KK74AC253N Plastic KK74AC253D 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 Output Enable Y X X H Z 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 Z = high impedance X = don’t care 1 KK74AC253 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 KK74AC253 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 * VIN= VIH or VIL IOH=-12 mA IOH=-24 mA IOH=-24 mA VOL Maximum LowLevel Output Voltage IOUT ≤ 50 µA V * IIN Maximum Input Leakage Current VIN=VCC or GND 5.5 ±0.1 ±1.0 µA IOZ Maximum ThreeState Leakage Current VIN (OE)= VIH or VIL VIN =VCC or GND VOUT =VCC or GND 5.5 ±0.5 ±5.0 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 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.
