The outputs havethe 3-STATE feature. When enabled, the outputs exhibitthe low impedance characteristics of a standard LS outputwith additional drive capability to permit the driving of buslines without external resistors. When disabled, both theoutput transistors are turned OFF presenting a high-imped-ance state to the bus line. Thus the output will act neitheras a significant load nor as a driver. To minimize the possi-bility that two outputs will attempt to take a common bus toopposite logic levels, the disable time is shorter than theenable time of the outputs.

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)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.Note 4: ICC is measured with the DATA inputs grounded and the OUTPUT CONTROLS at 4.5V.Note 5: Both G inputs are at 2V.Note 6: Both G inputs at 0.4V.Switching Characteristics at VCC = 5V and TA = 25°C Note 7: CL = 5 pF.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 −2.6 mAIOLLOW Level Output Current 24 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 = Max2.4 3.4 VOutput Voltage VIL = Max, VIH = MinVOLLOW Level VCC = Min, IOL = Max0.35 0.5Output Voltage VIL = Max, VIH = Min VIOL = 12 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 µAIIL LOW Level VCC = Max, VI = 0.5V (Note 5) A Input −20 µAInput Current VCC = Max, VI = 0.4V (Note 6) A Input −0.4mAVCC = Max, VI = 0.4V G Input −0.4IOZHOff-State Output Current with VCC = Max, VO = 2.4V20 µAHIGH Level Output Voltage Applied VIH = Min, VIL = MaxIOZLOff-State Output Current with VCC = Max, VO = 0.4V−20 µALOW Level Output Voltage Applied VIH = Min, VIL = MaxIOSShort Circuit Output Current VCC = Max (Note 3) −20 −100 mAICCSupply Current VCC = Max (Note 4) 14 24 mARL = 667ΩSymbol ParameterCL = 50 pF CL = 150 pFUnitsMin Max Min MaxtPLHPropagation Delay Time LOW-to-HIGH Level Output 16 25 nstPHLPropagation Delay Time HIGH-to-LOW Level Output 16 25 nstPZHOutput Enable Time to HIGH Level Output 30 40 nstPZLOutput Enable Time to LOW Level Output 30 40 nstPHZOutput Disable Time from HIGH Level Output (Note 7) 20 nstPLZOutput Disable Time from LOW Level Output (Note 7) 20 ns3 www.fairchildsemi.comDM74LS367APhysical Dimensions inches (millimeters) unless otherwise noted16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 NarrowPackage Number M16Awww.fairchildsemi.com 4DM74LS367A Hex 3-STATE Buffer/Bus DriverPhysical Dimensions inches (millimeters) unless otherwise noted (Continued)16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 WidePackage Number N16EFairchild 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.
