@ T2L inputs and outputs @ Delays stable and precise @ 38-pin DIP package _@ Leads - thru-hole, J, Gull Wing, or Tucked @ Available in delays from 5 to 250ns - each isolated and with 10 T2L fan-out capacity @ Two (2) separate isolated delay lines @ Rise time 4ns maximum design notes The "Mini DIP Series" Multiple Logic Delay Lines 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 DIP package compatible with FAST and Schottky TAL 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 elements. The MTBF on these modules, when calculated per MIL-HDBK-217 for a 50C ground fixed environment, is in excess of 1.5 million hours. Module design includes compensation for propagation delays and incorporates internal termination at the output; no additional external components are needed to obtain the desired delay. The MB2@FLDL-TTL is offered in 42 delays from 5 to 250ns, Each module includes two (2) separate delay lines, each isolated and fully buffered. Delay tolerances are maintained as shown in the accompa- nying part number table, when tested under the "Test Conditions shown. Delay time is measured at the+1.5 level onthe leading edge. 2 low profile TL COMPATIBLE LOGIC DELAYLINE Rise time for all modules is 4ns maximum when measured fram 0.8 to 2.0V. Temperature coefficient of delay is ap- proximately +1200 ppmiC over the operating temperature range of O ta +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 individual delay line has the capability of driving up to 10 Schottky T@L 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 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. 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 circult 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.

All measurements are made at 25C, Vee supply voltage is maintained at 5.0V DC. All units are tested using a Schottky toggle-type positive input pulse and one Schottky load at the output. Input pulse width used is 100% longer than delay of module under test; spacing between pulses (falling edge to rising edge) is three times the pulse width used.
