Surface Mount FAST TTL Logic Delay Module
The Surface Mount FAST TTL Logic Delay Modules manufactured by Engineered Components Company are
designed to provide output waveforms that reproduce the input waveform after a set amount of delay time
has elapsed. The five output waveforms are delay line taps provided at 20% increments of the total delay
(20, 40, 60, 80, and 100%). These delay modules are non-inverting. The delay times are calibrated to the
listed tolerances on the rising edge delays. The products with a total delay of less than 25ns have additional
delay present at tap 1 due to internal propagation delays (see the Product Selection Table).
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
500 ppm/deg.C over the operating temperature range of 0 to +70 deg. C.
The module is provided in a SO-14 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 8
beryllium copper leads are tin-lead plated and meet the solderability requirements of MIL-STD-202, Method 208.
