The device should not beoperated at these limits. The parametric values defined in the ElectricalCharacteristics tables are not guaranteed at the absolute maximum ratings.The “Recommended Operating Conditions” table will define the conditionsfor actual device operation.Recommended Operating ConditionsElectrical Characteristics over recommended operating free air temperature range (unless otherwise noted)Switching Characteristics at VCC = 5V and TA = 25°C Note 2: All typicals are at VCC = 5V, TA = 25°C.Note 3: Not more than one output should be shorted at a time, and the duration should not exceed one second.Supply Voltage 7VInput Voltage 7VOperating Free Air Temperature Range 0°C to +70°CStorage Temperature Range −65°C to +150°CSymbol Parameter Min Nom Max UnitsVCCSupply Voltage 4.75 5 5.25 VVIHHIGH Level Input Voltage 2 VVILLOW Level Input Voltage 0.8 VIOHHIGH Level Output Current −0.4 mAIOLLOW Level Output Current 8 mATAFree Air Operating Temperature 0 70 °CSymbol Parameter Conditions MinTypMax Units(Note 2)VIInput Clamp Voltage VCC = Min, II = −18 mA −1.5 VVOHHIGH Level VCC = Min, IOH = Max,2.7 3.4 VOutput Voltage VIH = MinVOLLOW Level VCC = Min, IOL = Max,0.35 0.5Output Voltage VIL = Max VIOL = 4 mA, VCC = Min 0.25 0.4IIInput Current @ Max Input Voltage VCC = Max, VI = 7V 0.1 mAIIHHIGH Level Input Current VCC = Max, VI = 2.7V 20 µAIILLOW Level Input Current VCC = Max, VI = 0.4V −0.36 mAIOSShort Circuit Output Current VCC = Max (Note 3) −20 −100 mAICCHSupply Current with Outputs HIGH VCC = Max 2.4 4.8 mAICCLSupply Current with Outputs LOW VCC = Max 4.4 8.8 mARL = 2 kΩSymbol Parameter CL = 15 pF CL = 50 pF UnitsMinMaxMinMaxtPLHPropagation Delay Time4 13 6 18 nsLOW-to-HIGH Level OutputtPHLPropagation Delay Time311518nsHIGH-to-LOW Level Output3 www.fairchildsemi.comDM74LS08Physical Dimensions inches (millimeters) unless otherwise noted14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150 NarrowPackage Number M14Awww.fairchildsemi.com 4DM74LS08Physical Dimensions inches (millimeters) unless otherwise noted (Continued)14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm WidePackage Number M14D5 www.fairchildsemi.comDM74LS08 Quad 2-Input AND GatesPhysical Dimensions inches (millimeters) unless otherwise noted (Continued)14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 WidePackage Number N14AFairchild does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied andFairchild reserves the right at any time without notice to change said circuitry and specifications.LIFE SUPPORT POLICYFAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORTDEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF FAIRCHILDSEMICONDUCTOR CORPORATION.
