@ TL input and outputs @ Delays stable and precise @ 8-pin DIP package 3g 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 "Mini DIF Series" Logic Delay Modules developed by Engi- neered Components Company have been designed to provide pre- cise delays with required driving and pick-off circuitry contained in a single 8-pin DIP package compatible with FAST and Schottky T@L 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 par MIL-HDBK-217 fora 50C ground fixedenvironment, 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 MDFLDM-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 +1.5V level on the leading edge. Rise time for 2 ee Mini DIP-443 LOGIC DELAY MODULE low profile TL COMPATIBLE all modules is 4ns maximum when measured fram 0.8 to 2.0V. Temperature coefficient of delay is approximately +500 ppm over the operating temperature range of Oto 470C, These modules accept either logic "1" or logic O 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 "Mini DIP Series modules are packaged in an 8-pin DIP housing, malded 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- S5TD-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, loga {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, ta meet the perma- nency of identification required by MIL-STD-202, Method 215.

All measurements are made at 25C. 2. Veo supply voltage is maintained at 5.0 DC, 3. All units are tested using a Schottky taggle-type positive input pulse and one Schottky load at the output being tested. 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.
