8-TAP, ECL-INTERFACEDFIXED DELAY LINE(SERIES DDU18)FEATURES PACKAGES• Eight equally spaced outputs• Fits in 400 mil 24-pin DIP socket• Input & outputs fully 100K-ECL interfaced & bufferedFUNCTIONAL DESCRIPTIONThe DDU18-series device is a 8-tap digitally buffered delay line. Thesignal input (IN) is reproduced at the outputs (T1-T8), shifted in time by anamount determined by the device dash number (See Table). For dashnumbers less than 16, the total delay of the line is measured from T1 toT8. The nominal tap-to-tap delay increment is given by one-seventh ofthe total delay, and the inherent delay from IN to T1 is nominally 2.0ns. For dash numbers greater than or equal to 16, the total delay of the line is measured from IN to T8. The nominal tap-to-tap delay incrementis given by one-eighth of this number.SERIES SPECIFICATIONS• Minimum input pulse width: 40% of total delay• Output rise time:2ns typical• Supply voltage:-5VDC ± 5%• Power dissipation: 500mw typical (no load)• Operating temperature: 0° to 85° C• Temp. coefficient of total delay: 100 PPM/°CVCC GNDIN T1T2T3T4Functional diagram for dash numbers < 16T5T6T7T8VCC GNDIN T1T2T3T4Functional diagram for dash numbers >= 16T5T6T7T8©1997 Data Delay Devicesdatadelaydevices, inc.®32419181313456789101112GNDT1T2T3GNDGNDT4T5T6T7T8INGNDVEEGNDGNDN/CT1T2T3GNDGNDT4T5T6T7T8INN/CN/CN/CN/CGNDVEEN/CN/CN/CN/CT10DDU18-xx DIPDDU18-xxM Military DIPDDU18-xxC3SMDDDU18-xxMC3Mil SMDPIN DESCRIPTIONSIN Signal InputT1-T8Tap OutputsVEE-5 VoltsGND GroundDASH NUMBER SPECIFICATIONSPartNumberTotalDelay (ns)Delay PerTap (ns)DDU18-4 3.5 ± 1.0 *0.5 ± 0.3DDU18-87.0 ± 1.0 * 1.0 ± 0.4DDU18-1210.5 ± 1.0 * 1.5 ± 0.4DDU18-1616 ± 1.0 2.0 ± 0.5DDU18-2020 ± 1.0 2.5 ± 1.0DDU18-2424 ± 1.2 3.0 ± 1.5DDU18-3232 ± 1.6 4.0 ± 2.0DDU18-4040 ± 2.0 5.0 ± 2.0DDU18-4848 ± 2.4 6.0 ± 2.0DDU18-5656 ± 2.87.0 ± 2.0DDU18-6464 ± 3.28.0 ± 2.0DDU18-7272 ± 3.69.0 ± 2.0DDU18-8080 ± 4.010.0 ± 2.5DDU18-100100 ± 5.012.5 ± 2.5DDU18-120120 ± 6.015.0 ± 3.0DDU18-160160 ± 8.020.0 ± 4.0DDU18-200200 ± 10.025.0 ± 5.0* Total delay is referenced to first tap outputInput to first tap = 2.0ns ± 1nsNOTE:Any dash number between 4 and 200not shown is also available.APPLICATION NOTESHIGH FREQUENCY RESPONSEThe DDU18 tolerances are guaranteed for input pulse widths and periods greater than those specified in the test conditions. Although the device will function properly for pulse widths as small as 40% of the total delay and periods as small as 80% of the total delay (for a symmetric input), the delays may deviate from their values at low frequency. However, for a given input condition, the deviation will be repeatable from pulse to pulse. Contact technical support at Data Delay Devices if your application requires device testing at a specific input condition.POWER SUPPLY BYPASSINGThe DDU18 relies on a stable power supply to produce repeatable delays within the stated tolerances. A 0.1uf capacitor from VEE to GND, located as close as possible to the VEE pin, is recommended. A wide VEE trace and a clean ground plane should be used.DEVICE SPECIFICATIONSTABLE 1: ABSOLUTE MAXIMUM RATINGSPARAMETER SYMBOL MIN MAX UNITS NOTES DC Supply Voltage V EE-7.00.3VInput Pin Voltage V IN V EE - 0.30.3VStorage Temperature T STRG-55150CLead Temperature T LEAD300C10 secTABLE 2: DC ELECTRICAL CHARACTERISTICS(0C to 85C)PARAMETER SYMBOL MIN TYP MAX UNITS NOTESHigh Level Output Voltage V OH-1.025-0.880V V IH = MAX,50Ω to -2V Low Level Output Voltage V OL-1.810-1.620V V IL = MIN, 50Ω to -2V High Level Input Voltage V IH-1.165-0.880VLow Level Input Voltage V IL-1.810-1.475VHigh Level Input Current I IH340µA V IH = MAXLow Level Input Current I IL0.5µA V IL = MINPACKAGE DIMENSIONSDDU18-xx (Commercial DIP)DDU18-xxM (Military DIP).015DDU18-xxC4 (Commercial SMD)DDU18-xxMC4 (Military SMD)DELAY LINE AUTOMATED TESTINGTEST CONDITIONSINPUT:OUTPUT:Ambient Temperature:25o C ± 3o C Load:50Ω to -2V Supply Voltage (Vcc):-5.0V ± 0.1V C load :5pf ± 10%Input Pulse:Standard 10KH ECLThreshold:(V OH + V OL ) / 2levels(Rising & Falling)Source Impedance:50Ω Max.Rise/Fall Time: 2.0 ns Max.

Use a rubber mallet or softblock of wood to loosen impeller.Turn it counterclockwise.Disconnectspark plug wireand battery toprevent accidental starting.3993-251-00 03/20114.Unthread cap screws (Ref. No. 4)and remove the adapter from theengine mounting face.5.Push seal seat from the adapterrecess with a screwdriver.6.Clean the adapter recess beforeinserting a new seal seat.7.Carefully wipe the polishedsurface of the new seal seat witha clean cloth.8.Wet the rubber portion of the sealseat with a light coating of soapywater.9.Press the new seal seat squarelyinto the cavity in the adapter. Ifthe seal seat does not presssquarely into the cavity, it can beadjusted in place by pushing on itwith a piece of pipe. Always use apiece of cardboard between thepipe and the seal seat to avoidscratching the seal seat. (This is alapped surface and must behandled very carefully).10.After the seal seat is in place,ensure that it is clean and has notbeen marred.ing a clean cloth, wipe the shaftand make certain that it isperfectly clean.12.Secure the adapter on the enginemounting face.NOTE: Tighten cap screws EVENLY to avoid cocking rabbet on engine mounting face.13.Apply a light coating of soapywater to the inside rubber portionof seal head and slide onto theshaft sleeve. Slip the shaft sleevewith seal head onto the engineshaft.IMPORTANT: Before installing new shaft sleeve, apply a bead of non-hardening, pliable sealant (such as Permatex® Form-A-Gasket® No. 2) to motor shaft shoulder.Do not touch orwipe the face of the polished part of the seal head.14.Replace any impeller shimsremoved in disassembly.15.Screw the impeller back in placetightening until it is seated againstshims and shaft sleeve.NOTE: Check to ensure that the shaft flange (Ref. No. 2) is in place against engine shaft shoulder.16.Remount volute with fasteners.17.Refer to section titled ShimAdjustment at this time if shaftsleeve or any other parts listedtherein have been replaced.18.Inspect position of flapper valveassembly (Ref. No. 16) to ensureproper movement and sealing.19.Replace O-ring seal on voluterabbet.NOTE: Always inspect O-ring seals.Replace when cracked or worn. WetO-ring with soapy water for ease ofassembly.20.Remount casing.21.Remount any other parts andreconnect spark plug wire andbattery (if so equipped). Pumpshould now run with renewedoriginal performance.SHIM ADJUSTMENT1.When installing a replacementimpeller, engine, shaft sleeve,adapter, or volute, it may benecessary to vary the number ofimpeller shims (Ref. No. 11) that willbe required. This is easily done byadding one shim more than wasremoved and reassembling thepump as described in MechanicalSeal Replacement section.2.Ensure that volute (Ref. No. 13) andadapter (Ref. No. 6) are fitted firmly(check fastener Ref. No. 4 and 14).Remove spark plug wire from engineand turn engine over by pulling therecoil starter. If engine does not turnfreely, disassemble pump andremove one shim.NOTE: When adding or removing shims,it is best to proceed with a 0.010"increment each time. If engine does turnfreely, add shims until it does strike, thenremove a 0.010" shim. This should allowproper clearance.3.Proper running clearance is 0.010".4.Follow the above procedure untilproper clearance is obtained. Thiswill ensure maximum performance.IMPELLER AND WEARPLATEREPLACEMENTImpeller (Ref. No. 13) and volute/wearplate (Ref. No. 14) are subject towear only by abrasive sand or sedimentladen liquids. If badly worn, all theseparts can be replaced easily and thepump thus restored to full efficiency.NOTE: When the clearance between theimpeller and the volute/wearplateexceeds 1/16" at the face of the impelleror 1/8" on the outside diameter of theimpeller, it may be necessary to takecorrective action. The increasedclearance can cause lengthenedpriming times and reduced pumpingcapacity. If both the priming andcapacity of your unit are satisfactory foryour application, it is recommended thatno corrective maintenance beperformed regardless of whatclearances on your unit may havedeveloped, since the increasedclearances in themselves are notgenerally harmful to your pump.Normally, new pump clearances can berestored by simply shimming behind theimpeller. (Add shim washers, Ref. No.11). If the impeller is badly worn it isrecommended that the impeller bereplaced. This is usually all that isrequired since only on unusuallyabrasive services does the cast ironwearplate show deterioration.Occasionally a stone or hard objectmight get caught in the impeller andcause damage to the volute/cutwater. Inthese cases, follow the instructionsbelow for replacement and refer toFigure 2.1.Disassemble pump for access asdescribed in MECHANICAL SEALREPLACEMENT, steps 1 and 2.2.Replace parts as necessary.NOTE: When replacing volute, attachflapper valve assembly (Ref. No. 16) tonew volute with fasteners (Ref. No. 17).NOTE: Before installing new parts,clean all mating surfaces thoroughly.For information pertaining to the engineand engine parts, consult the EngineManual or contact the nearestauthorized service representative or themanufacturer.CLEANINGThese units are designed so that formost cleanout or clogging problems itshould not be necessary to removehoses or piping. The suction area andimpeller chambers can be reached byremoving (2) threaded handles (Ref. No.25) and removing suction cleanoutcover plate (Ref. No. 27) and gasket(Ref. No. 28).NOTE: When replacing cleanout coverplate, carefully wipe clean all surfaceson which the gasket has contact. Also,make sure the gasket is in position. Thescreen in the spark arrester should bechecked.Specifications Information and Repair Parts Manual3993-96, 3993-D6, 3994-96 and 4120-964。

Using a chop saw with a 3 h.p. motorand a metal cutting blade helps to insure a cleanedge with no burrs.2.FRAME ASSEMBLY ANDSEATING Using a mallet, insert the cor-ners into the shorter angles; install the largerangles to complete the frame. The raised portionof the corner should be facing inward with the“Ward” name visible from the outside.Starting at a corner, using a mallet, hammer thecompleted frame onto the raw edge of the ductsection. Moving in one direction, make sure theduct is seated into the mastic.NOTE: The duct section should not be notched.3.FASTENING THE FRAMEThe frame can be fastened to the ductwork witheither Hex Tex screws (10 x 3/4) or spot welds.NOTE: On installations of 3” s.p. or above or onsystems where leakage is to be less than 1%,spot welding is recommended.Tek screwing of the angle or spot welding muststart within 3/4” of each end of the angle at theduct section corners.(See Chart on next page.)Important: since sheet metal ductwork installations are sometimes used by the other trades as scaffolding, actual job con-ditions should really dictate the amount of spot welding and tek screwing.5.INSTALLING THE CLEAT Snap a 4”piece of either metal or PVC cleat over the mating frames,using the following recommendations:1/2” to 2” sp — 1 piece on 24” centers 2” to 3” sp — 1 piece on 18” centers 4” to 6” sp — 1 piece on 12” centers Over 10” sp — continuous cleatNOTE: On installations where the operating pressures are 4”or higher and the leakage requirements are less than 3%special care must be given to the treatment of the corners.Special butyl patches (2” x 3”) are available.1/2” W.G.Static pos or neg Duct Dimen.SHOP STANDARDSALUMINUM RECTANGULAR DUCT REINFORCEMENTWard J Flange - Roll Formed from .063 Aluminum Minimum Gauge Duct - Reinforcement Spacing54”-Down 55”-60”61”-72”73”-84”85”-96”97”-108”109”-120”5’0.0320.040.050.050.0634’0.0320.040.040.040.052 1/2’0.0320.0320.040.040.050.0710.0712’0.0320.0320.040.040.050.0710.0713” W.G.Static pos or neg Duct Dimen.SHOP STANDARDSALUMINUM RECTANGULAR DUCT REINFORCEMENTWard J Flange - Roll Formed from .063 Aluminum Minimum Gauge Duct - Reinforcement Spacing12”-Down 13”-26”27”-30”31”-36”37”-42”43”-48”49”-54”55”-60”5’0.0320.040.050.0630.0634’0.0320.040.040.050.050.0632 1/2’0.0320.0320.0320.0320.040.040.040.052’0.0320.0320.0320.0320.0320.040.040.044” W.G.Static pos or neg Duct Dimen.SHOP STANDARDSALUMINUM RECTANGULAR DUCT REINFORCEMENTWard J Flange - Roll Formed from .063 Aluminum Minimum Gauge Duct - Reinforcement Spacing12”-Down 13”-26”27”-30”31”-36”37”-42”43”-48”49”-54”55”-60”5’0.0320.040.050.0634’0.0320.040.040.050.0632 1/2’0.0320.0320.0320.0320.040.040.052’0.0320.0320.0320.0320.0320.040.040.052” W.G.Static pos or neg Duct Dimen.SHOP STANDARDSALUMINUM RECTANGULAR DUCT REINFORCEMENTWard J Flange - Roll Formed from .063 Aluminum Minimum Gauge Duct - Reinforcement Spacing26”-Down 27”-30”31”-36”37”-42”43”-48”49”-54”55”-60” 61”-72”5’0.0320.040.050.0630.0630.0714’0.0320.0320.040.040.050.0630.0712 1/2’0.0320.0320.0320.040.040.04 0.040.052’0.0320.0320.0320.040.040.040.040.046” W.G.Static pos or neg Duct Dimen.SHOP STANDARDSALUMINUM RECTANGULAR DUCT REINFORCEMENTWard J Flange - Roll Formed from .063 Aluminum Minimum Gauge Duct - Reinforcement Spacing12”-Down 13”-24”25”-28”29”-30”31”-36”37”-42”43”-48”5’0.040.050.0630.0714’0.0320.050.050.050.0712 1/2’0.0320.0320.040.040.040.052’0.0320.0320.040.040.040.050.0631” W.G.Static pos or neg Duct Dimen.SHOP STANDARDSALUMINUM RECTANGULAR DUCT REINFORCEMENTWard J Flange - Roll Formed from .063 Aluminum Minimum Gauge Duct - Reinforcement Spacing30”-Down 31”-42”43”-60”61”-72”73”-84”85”-96”5’0.0320.040.050.0714’0.0320.0320.040.052 1/2’0.0320.0320.040.040.050.0632’0.0320.0320.040.040.050.0510” W.G.Static pos or neg Duct Dimen.SHOP STANDARDSALUMINUM RECTANGULAR DUCT REINFORCEMENTWard J Flange - Roll Formed from .063 Aluminum Minimum Gauge Duct - Reinforcement Spacing8”-Down 9”-12”13”-18”19”-26”27”-30”31”-36”5’0.040.050.0630.0714’0.0320.040.0630.0632 1/2’0.0320.0320.040.050.050.0632’0.0320.0320.0320.050.050.05ALUMINUM RECTANGULAR DUCT REINFORCEMENTSHOP STANDARDS RECTANGULAR INDUSTRIAL DUCT REINFORCEMENT CLASS 1 SYSTEM CLASSIFICATIONFlangeJJJJJJ JT JT JT JT JT JT JT Static Pressure17”17”17”17”17”15”15”9”6”4”3”2”1.5”Duct Size 12-18”19-24”25-30”31-36”37-42”43-48”49-60”61-72”73-84”85-96”97-108”109-120”121-144”2’0”Duct Section16 GA14 GA16 GA14 GA4’0”Duct SectionFlangeJJJJJJJTJTJTJTJTJTJTStatic Pressure22”22”22”22”22”15”15”9”6”4”3”2”1.5”FlangeJJJJJJJTJTJTJTStatic Pressure8”8”8”8”8”8”7”4”3”2”1.5”1”.5”FlangeJJJJJJJTJTJTJTJTStatic Pressure11”11”11”11”11”8”8”4”3”2”1.5”1”.5”COMMENTARYThe Ward J Flange was specifically designed to recieve 14 ga.sheetmetal material.We have listed below some possible uses of the J Flange with 16 ga.and 14 ga.sheetmetal material.These are some typical uses, however, Ward Industries will furnish the necessaryengineering calculations for other applications.GALVANIZED STEEL TRAPEZEHANGERS FOR DUCTWORK– NOTES –COPYRIGHT©1998WARD INDUSTRIES。

FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DDU18-series device is a 8-tap digitally buffered delay line. The IN Signal Input signal input (IN) is reproduced at the outputs (T1-T8), shifted in time by an T1-T8 Tap Outputs amount determined by the device dash number (See Table). For dash VEE -5 Volts numbers less than 16, the total delay of the line is measured from T1 to GND Ground T8. The nominal tap-to-tap delay increment is given by one-seventh of the total delay, and the inherent delay from IN to T1 is nominally 2.0ns. For dash numbers greater than or equal to 16, the total delay of the line is measured from IN to T8. The nominal tap-to-tap delay increment is given by one-eighth of this number.

APPLICATION NOTES
HIGH FREQUENCY RESPONSE
The DDU18 tolerances are guaranteed for input pulse widths and periods greater than those specified in the test conditions. Although the device will function properly for pulse widths as small as 40% of the total delay and periods as small as 80% of the total delay (for a symmetric input), the delays may deviate from their values at low frequency. However, for a given input condition, the deviation will be repeatable from pulse to pulse. Contact technical support at Data Delay Devices if your application requires device testing at a specific input condition.
