@ T2L FAST input and output @ Delay stable and precise @ 8-pin DIP package @ Leads Thru-hole, J, Gull Wing or Tucked @ Available in delays from 5 to 500ns @ Output isolated and with 10 T2L fan-out capacity @ Rise time 4ns maximum design notes The "Mini Dip Series" Logic Delay Lines developed by Engi- neered Components Company have been designed to provide precise delays with required driving and pick-off circuitry contained ina single &-pin DIP package compatible with FAST TL circuits. These logic delay lines are of hybrid construction utilizing the proven technologies of active integrated circuitry and of passive networks utilizing capacitive, inductive and resistive elaments. The MTBF on these modules, when calculated per MIL-HDBK-217 for a 50C ground fixed environment, is in excess of 3 million hours. Module design includes compensation for propagation delays and incorporates internal termination at the oulpul; no additional external components are needed to obtain the desired delay. The MBFLDL-TTL is offered in 48 delays fram Sns to 500ns. Delay tolerances are maintained as shown in the accompanying r low profile rs COMPATIBLE Mini DIP LOGIC DELAY LINE part number table, when tested under the Test Conditions" shawn, Delay time is measured at the +1.5V level on the leading edge. Rise time for all modules is 4ns maximum when measured from 0.75 to 2.4V. Temperature coefficient of delay is approximately +1200 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 applications 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 10 TL loads. These "Mini DIP Series" modules are packaged in an 8-pin DIP housing, molded of flame-proof Diallyl Phthalate per MIL-M-14, Type SOG-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, Corner standoffs on the housing of the thru-hole lead version and lead design of the surface mountversions 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 logo (EC*), Federal Supply Code, part number, pin one (1) identification and date code of manufacture. Allmarking 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. engineered components company 3580 SACRAMENTO DRIVE @ P.O.
