@ 121 input and output @ Delay stable and precise @ 8-pin Space Saver package ~@ Leads - thru-hole, J, Gull Wing or Tucked @ Available in delays from 5 to 500ns @ Rise time 4ns maximum design notes The "Space Saver Series" Logic Delay Lines developed by Engi- neered Camponents Company have been designed to provide pre- cise delays with required driving and pick-off circuitry contained in a single 8-pin package compatible with FAST and Schottky T*Leircuits. 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 far a 50C ground fixed environment, is in excess of 3 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 SSFLDL-TTL is offered in 48 delays from 5 to 500ns. 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 +1.5V level on the leading edge. Rise time for 2 yt COMPATIBLE FAST -LOGIC DELAY LINE all modules is 4ns maximum when measured from 0.8V to 2.0V. Temperature coefficient of delay is approximately +1200 ppm"C over the operating temperature range of 0 to +FOC, These modules accept either logic "1" or logic "0" inputs and reproduce the logic at the output without inversion, The delay madules 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 upto 10 Schottky T?Lloads. 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- 70-202, 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.

Tucked Lead TEST CONDITIONS 1. All measurements are made at 25C, 2. Vee supply voltage is maintained at 5.0 DC. 3. All units are tested using a Schottky toggle-type positive input pulse and one Schottky load at the output. a4. 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.
