© 2000 Fairchild Semiconductor Corporation DS010620November 1989Revised February 2000DM74ALS125 Quad 3-STATE BufferDM74ALS125Quad 3-STATE BufferGeneral DescriptionThis device contains four independent gates each of which performs a non-inverting buffer function. The outputs have the 3-STATE feature. The 3-STATE circuitry contains a fea-ture that maintains the buffer outputs in 3-STATE (high impedance state) during power supply ramp-up or ramp-down. This eliminates bus glitching problems that arise during power-up and power-down. To minimize the possi-bility that two outputs will attempt to take a common bus to opposite logic levels, the disable time is shorter than the enable time of the outputs.Featuress Advanced low power oxide-isolated ion-implanted Schottky TTL process s Functional and pin compatible with the 74LS counterpart s Switching response specified into 500Ω and 50 pF load s Switching response specifications guaranteed over full temperature and V CC supply range s PNP input design reduces input loading s Low level drive current: 74ALS = 24 mAOrdering Code:Devices also available in T ape and Reel. Specify by appending the suffix letter “X” to the ordering code.Connection Diagram Functional TableY = AH = HIGH Logic Level L = LOW Logic LevelX = Either LOW or HIGH Logic Level Hi-Z = 3-STATE (Outputs are disabled)Logic DiagramOrder Number Package NumberPackage DescriptionDM74ALS125M M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow DM74ALS125NN14A14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 WideInput Output A C Y L L L H L H XHHi-Z 2D M 74A L S 125Absolute Maximum Ratings (Note 1)Note 1: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.The “Recommended Operating Conditions” table will define the conditions for actual device operation.Recommended Operating ConditionsElectrical Characteristicsover recommended operating free air temperature (unless otherwise specified)Supply Voltage, V CC 7V Input Voltage7V Voltage Applied to Disabled Output 5.5V Operating Free Air Temperature Range 0 to +70°C Storage Temperature Range −65°C to +150°CTypical θJA N Package 78.0°C/W M Package111.0°C/WSymbol ParameterMin Typ Max Units V CC Supply Voltage4.555.5V V IH HIGH Level Input Voltage 2V V IL LOW Level Input Voltage 0.8V I OH HIGH Level Output Current −15mA I OL LOW Level Output Current 24mA T AOperating Free-Air Temperature70°CSymbol ParameterConditionsMinTypMax Units V IK Input Clamp Voltage V CC = 4.5V, I I = −18 mA −1.5V V OHHIGH Level V CC = 4.5V to 5.5V I OH = −0.4 mA V CC −2V Output VoltageV CC = 4.5V I OH = −3 mA 2.4V I OH = Max 2V V OL LOW Level V CC = 4.5VI OL = 12 mA 0.250.4V Output Voltage I OL = 24 mA0.350.5V I I Input Current at Max V CC = 5.5V, V I = 7V 0.1mA Input Voltage I IH HIGH Level V CC = 5.5V, V I = 2.7V 20µA Input Current I IL LOW Level V CC = 5.5V, V IL = 0.4V −0.1mA Input Current I O Output Drive V CC = 5.5V, V O = 2.25V −30−112mA CurrentI OZH HIGH Level 3-STATE V CC = 5.5V, V O = 2.7V 20µA Output Current I OZL LOW Level 3-STATE V CC = 5.5V, V O = 0.4V −20µA Output Current I CCSupply CurrentV CC = 5.5VOutputs HIGH 710mA Outputs LOW 1014mA 3-STATE13.518mADM74ALS125Switching CharacteristicsSymbol ParameterFrom To Conditions Min MaxUnits (Input)(Output)t PLH Propagation Delay Time A Y V CC = 4.5V to 5.5V,310ns LOW-to-HIGH Level Output C L = 50 pF,t PHL Propagation Delay Time A Y R1 = 500Ω,210ns HIGH-to-LOW Level Output R2 = 500Ω,t PZH Output Enable Time C Y T A = Min to Max213ns to HIGH Level Output t PZL Output Enable Time C Y 212ns to LOW Level Output t PHZ Output Disable Time C Y 18ns from HIGH Level Output t PLZOutput Disable Time CY213nsfrom LOW Level Output 4D M 74A L S 125Physical Dimensionsinches (millimeters) unless otherwise noted14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 NarrowPackage Number M14A5DM74ALS125 Quad 3-STATE BufferPhysical 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 and Fairchild 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 SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF FAIRCHILD SEMICONDUCTOR CORPORATION.

discontinued,and a lifetime-buy period is in effect.NRND:Not recommended for new designs.Device is in production to support existing customers,but TI does not recommend using this part in a new design.PREVIEW:Device has been announced but is not in production.Samples may or may not be available.OBSOLETE:TI has discontinued the production of the device.(2)Eco Plan-The planned eco-friendly classification:Pb-Free(RoHS),Pb-Free(RoHS Exempt),or Green(RoHS&no Sb/Br)-please check /productcontent for the latest availability information and additional product content details.TBD:The Pb-Free/Green conversion plan has not been defined.Pb-Free(RoHS):TI's terms"Lead-Free"or"Pb-Free"mean semiconductor products that are compatible with the current RoHS requirements for all6substances,including the requirement that lead not exceed0.1%by weight in homogeneous materials.Where designed to be soldered at high temperatures,TI Pb-Free products are suitable for use in specified lead-free processes.Pb-Free(RoHS Exempt):This component has a RoHS exemption for either1)lead-based flip-chip solder bumps used between the die and package,or2)lead-based die adhesive used between the die and leadframe.The component is otherwise considered Pb-Free(RoHS compatible)as defined above.Green(RoHS&no Sb/Br):TI defines"Green"to mean Pb-Free(RoHS compatible),and free of Bromine(Br)and Antimony(Sb)based flame retardants(Br or Sb do not exceed0.1%by weight in homogeneous material)(3)MSL,Peak Temp.--The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications,and peak solder temperature.Important Information and Disclaimer:The information provided on this page represents TI's knowledge and belief as of the date that it
