FAST TTL Logic Delay Module
The 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
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.
