IN74ACT08 QUAD 2-INPUT AND GATE High-Speed Silicon-Gate CMOS • • • • The IN74ACT08 is identical in pinout to the LS/ALS08, HC/HCT08. The IN74ACT08 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. • 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 µA; 0.1 µA @ 25°C Outputs Source/Sink 24 mA ORDERING INFORMATION IN74ACT08N Plastic IN74ACT08D SOIC TA = -40° to 85° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs Output A B Y L L L L H L H L L H H H PIN 14 =VCC PIN 7 = GND 1 IN74ACT08 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) -0.5 to VCC +0.5 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 Sink/Source Current, per Pin mA ±50 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 IN74ACT08 DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) Guaranteed VCC Limits Symbol Parameter Test Conditions V 25 °C -40°C to 85°C VIH Minimum High- VOUT=0.1 V or VCC-0.1 V 4.5 2.0 2.0 Level Input 5.5 2.0 2.0 Voltage VIL Maximum Low - VOUT=0.1 V 4.5 0.8 0.8 Level Input 5.5 0.8 0.8 Voltage VOH Minimum High- IOUT ≤ -50 µA 4.5 4.4 4.4 Level Output 5.5 5.4 5.4 Voltage * VIN=VIH 3.76 3.86 IOH=-24 mA 4.5 4.76 4.86 5.5 IOH=-24 mA VOL Maximum Low- IOUT ≤ 50 µA 4.5 0.1 0.1 Level Output 5.5 0.1 0.1 Voltage * VIN=VIL or VIH 0.44 0.36 IOL=24 mA 4.5 0.44 0.36 5.5 IOL=24 mA IIN Maximum Input VIN=VCC or GND 5.5 ±0.1 ±1.0 Leakage Current 5.5 1.5 Additional Max VIN=VCC - 2.1 V ∆ICCT ICC/Input VOLD=1.65 V Max IOLD +Minimum 5.5 75 Dynamic Output Current VOHD=3.85 V Min IOHD +Minimum 5.5 -75 Dynamic Output Current VIN=VCC or GND ICC Maximum 5.5 4.0 40 Quiescent Supply Current (per Package) * All outputs loaded; thresholds on input associated with output under test. +Maximum test duration 2.0 ms, one output loaded at a time. 3 Unit V V V V µA mA mA mA µA IN74ACT08 AC ELECTRICAL CHARACTERISTICS(VCC=5.0 V ± 10%, CL=50pF,Input tr=tf=3.0 ns) Guaranteed Limits Unit Symbol Parameter 25 °C -40°C to 85°C Min Max Min Max tPLH Propagation Delay, Input A or B to 1.0 9.0 1.0 10.0 ns Output Y (Figure 1) tPHL Propagation Delay, Input A or B to 1.0 9.0 1.0 10.0 ns Output Y (Figure 1) CIN Maximum Input Capacitance 4.5 4.5 pF CPD Typical @25°C,VCC=5.0 V 20 Power Dissipation Capacitance Figure 1.
