Space Saver FAST TTL Logic Delay Line
The Space Saver FAST TTL Logic Delay Lines manufactured by Engineered Components Company are designed to provide
an output waveform that reproduces the input waveform after a set amount of delay time has elapsed. These delay
lines are non-inverting. The delay times are calibrated to the listed tolerances on the rising edge delays.
The MTBF on these modules, when calculated per MIL-HDBK-217, for a 50 deg.C ground fixed environment and with
50VDC applied, is in excess of 3 million hours. The temperature coefficient of delay is less than 1200 ppm/deg.C over
the operating temperature range of 0 to +70 deg. C.
The module is provided in a 8-pin Space Saver package, fully encapsulated in epoxy resin and is housed in a Diallyl
Phthalate case, blue in color. The case marking is applied by silkscreen using white epoxy paint. The 4 copper leads are
tin-lead plated and meet the solderability requirements of MIL-STD-202, Method 208.
