@ T2L input and outputs @ Delays stable and precise @ 14-pin DIP package Se Leads - thru-hole, J, Gull Wing or Tucked @ Available in delays from 15 to 1000ns @ Output and nine (9) taps - each isolated and with 10 T@L fan-out capacity @ Fast rise time on all outputs design notes The "DIP Series* Logic Delay Modules developed by Engineered Components Company have been designed to provide precise tapped delays with required driving and pick-off circuitry contained in a single 14-pin DIP 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 fora 50C ground fixed environment, 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 EFXLDM-TTL is offered in 27 delays from 15 to 1000ns with each module incorporating total output and nine (9) taps. Delay tolerances are maintained as shown in the accompanying part number table, when tested under the "Test Conditions shown. Delay 2 L engineered components company low profile TL COMPATIBLE FASEAOGIC DELAY MODULE time is measured at the +1.5V level on the leading edge. Rise time for all modules is 4ns maximum when measured from 0.8V to 2.0V. Temperature coefficient of delay is approxi- mately +400 ppmv/"C aver the operating temperature range of Oto +7050. 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 T?Lloads with a maximum of 10 loads on any one tap. These DIP Series* modules are packaged in a 14-pin DIP 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 ta specify). Leads meet the solderability requirements of MIL-STD-202, Method 208. Corner 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 solder-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. 3580 Sacramento Drive, P.O.
