FAST TTL Logic Delay Module (Thin Profile Package)
The FAST TTL Logic Delay Modules (Thin Profile Package) 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 2 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 14-pin DIP 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
copper leads are tin-lead plated and meet the solderability requirements of MIL-STD-202, Method 208.
