@ TL input and outputs @ Delays stable and precise @ &-pin Space Saver package ) Leads - thru-hole, J, Gull Wing or Tucked @ Available in delays from 10 to 500ns _ @ Output and four (4) taps - each isolated and with 10 T2L fan-out capacity @ Fast rise time on all outputs design notes The "Space Saver Series" Logic Delay Modules developed by Engineered Components Company have been designed to provide precise delays with required driving and pick-off circuitry contained in a single 8-pin package compatible with FAST and Schottky TAL circuits. These logic delay modules are of hybrid construction utilizing the proven technologies of active integrated circuitry and of passive networks utilizing capacitive, inductive and resistive elements. The MTBF on these modules, when calculated per MIL-HDBK-217 for a 50C ground fixed enviranment, isin excess of 2 million hours. Module design includes compensation for propagation delays and incorpo- rates internal termination at the output, no additional external compo- nents are needed to obtain the desired delay. The SSFLDM-TTL is offered in 33 delays from 10 to 500ns with each module incorporating total output and four (4) taps. Delay tolerances are maintained as shown in the accompanying part number table, when tested under the "Test Conditions" shown, Delay time is measured at the +1.5 level on the leading edge. L engineered components company 3580 Sacramento Drive, P.O. Box 8121, San Luis Obispo, CA 93403-8121 Phone: (805) 544-3800 ac COMPATIBLE Rise time for all modules is 4ns maximum when measured from 0.8V to 2.0V. Temperature coefficient of delay is ap- proximately +500 ppm/C over the operating temperature range of 0 to +70C, These modules accept either logic "1" or logic "0" inputs and reproduce the logic at the output without inversion. The delay modules are intended primarily for use with positive going pulses and are calibrated to the tolerances shown in the table on rising edge delay; where best accuracy is desired in appli- cations using falling edge timing, it is recommended that a special unit be calibrated for the specific application. Each module has the capability of driving up to 20 Schottky TL loads with a maximum of 10 loads on any one tap. These "Space Saver Series" modules are packaged in an 8- pin housing, molded of flame-proof Diallyl Phthalate per MIL-M- 14, Type SDG-F, and are fully encapsulated in epoxy resin. Thru-hole, J, Gull Wing or Tucked Lead configurations are available on these modules (see Part Number Table note to specify). Leads meet the solderability requirements of MIL- STD-202, Method 208. Comer standoffs on the housing of the thru-hole lead version and lead design of the surface mount versions provide positive standoff from the printed circuit board to permit selder-fillet formation and flush cleaning of solder-flux residues for improved reliability. Marking consists of manufacturer's name, logo (EC), part number, terminal identification and date code of manufacture, All marking is applied by silk screen process using white epoxy paint in accordance with MIL-STD-130, to meet the perma- nency of identification required by MIL-STD-202, Method 215.BLOCK DIAGRAM IS SHOWN BELOW Voc TAP 1 TAP 3 OUTPUT 8 7 6 5 oO ly x x l INPUT Ly DELAY LINE WITH | DRIVER T?L PICKOFF | | L L 4 TAP 4 GROUND MECHANICAL DETAIL IS SHOWN BELOW ae Pin No. Ef: ss vo o41 43 OUT SSFLDM- @TTL-___ IN 2 4 Pin No. 12 3 4 . 7307 | O60 p - TYP. 020 DIA, TYP. 21a | fe toa Te. f a PS ofc Oy 36d 4 + + 50 | | icone LO O10 9 zt = - = M125 , Thru-hole Lead i w a (O20 pe a 100 TYF vowel Tes | + | 1 a5 301 vP.-| + *Gull Wing Lead - 25 rt ara =e TOO TYR. p10 | | ive 95 Fi | | \ O30 TYP. te] fae j 150 ie be ae *J Lead ' | 020 oy a . | |e a [ -TBOTYE ro ; FA 3G5 vib t 235 | BE aac ORO TYP | | *Tucked Lead TEST CONDITIONS 1. All measurements are made at 25C. 2. Veo supply voltage is maintained at 5.0V DC. 3. All units are tested using a Schottky toggle-type positive input pulse and one Schottky load at the output being tested. @4. Input pulse width used is 5 to 10ns longer than delay of module under test; spacing between pulses (falling edge to rising edge) is three times the pulse width used.
