| IN74HCT153 DUAL 4-INPUT DATA SELECTOR/MULTIPLEXER High-Performance Silicon-Gate CMOS The IN74HCT153 is identical in pinout to the LS/ALS153. The IN74HCT153 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The Address Inputs select one of four Data Inputs from each multiplexer. Each multiplexer has an active-low Strobe control and a noninverting output. * TTL/NMOS Compatible Input Levels * Outputs Directly Interface to CMOS, NMOS, and TTL * Operating Voltage Range: 4.5 to 5.5 V * Low Input Current: 1.0 A ORDERING INFORMATION IN74HCT153N Plastic IN74HCT153D SOIC TA = -55 to 125 C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 16 =VCC PIN 8 = GND FUNCTION TABLE Inputs Output A1 A0 Strob Y e 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 1 IN74HCT153 MAXIMUM RATINGS* Symbol Parameter Value Unit VCC DC Supply Voltage (Referenced to GND) -0.5 to +7.0 V VIN DC Input Voltage (Referenced to GND) -1.5 to VCC +1.5 V VOUT DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V IIN DC Input Current, per Pin mA 20 IOUT DC Output Current, per Pin mA 25 ICC DC Supply Current, VCC and GND Pins mA 50 PD Power Dissipation in Still Air, Plastic DIP+ 750 mW SOIC Package+ 500 Tstg Storage Temperature -65 to +150 C 260 TL Lead Temperature, 1 mm from Case for 10 C 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 IN74HCT153 DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) Guaranteed Limit VCC Symbol Parameter Test Conditions V 85 125 25 C to C C -55C VIH Minimum High- VOUT=0.1 V or VCC-0.1 V 4.5 2.0 2.0 2.0 Level Input IOUT 20 A 5.5 2.0 2.0 2.0 Voltage VIL Maximum Low - VOUT=0.1 V or VCC-0.1 V 4.5 0.8 0.8 0.8 Level Input IOUT 20 A 5.5 0.8 0.8 0.8 Voltage VOH Minimum High- VIN=VIH or VIL 4.5 4.4 4.4 4.4 Level Output IOUT 20 A 5.5 5.4 5.4 5.4 Voltage VIN=VIH or VIL 4.5 3.98 3.84 3.7 IOUT 4.0 mA VOL Maximum Low- VIN=VIH or VIL 4.5 0.1 0.1 0.1 Level Output IOUT 20 A 5.5 0.1 0.1 0.1 Voltage VIN=VIH or VIL 4.5 0.26 0.33 0.4 IOUT 4.0 mA IIN Maximum Input VIN=VCC or GND 5.5 0.1 1.0 1.0 Leakage Current VIN=VCC ICC Maximum or GND 5.5 4.0 40 160 Quiescent Supply IOUT=0A Current (per Package) VIN = 2.4 V, Any One Additional -55C 25C to ICC Quiescent Supply Input 125C VIN=VCC or GND, Other Current Inputs 5.5 2.9 2.4 IOUT=0A Unit V V V V A A mA 3 IN74HCT153 AC ELECTRICAL CHARACTERISTICS(VCC=5.0 V 10%, CL=50pF,Input tr=tf=6.0 ns) Guaranteed Limit Unit Symbol Parameter 25 C 85C 125 to C -55C tPLH, Maximum Propagation Delay, Input D to 34 43 51 ns tPHL Output Y (Figures 1 and 4) tPLH, Maximum Propagation Delay , Input A to 34 43 51 ns tPHL Output Y (Figures 2 and 4) tPLH, Maximum Propagation Delay , Strobe to 27 34 41 ns tPHL Output Y (Figures 3 and 4) 15 19 22 ns tTLH, tTHL Maximum Output Transition Time, Any Output (Figures 1 and 4) CIN Maximum Input Capacitance 10 10 10 pF Power Dissipation Capacitance (Per Muliplexer) Used to determine the no-load dynamic power consumption: PD=CPDVCC2f+ICCVCC Typical @25C,VCC=5.0 V 40 CPD pF Figure 1.
