Advanced CMOS Logic Delay Module
The Advanced CMOS 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 30ns 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 1.3 million hours. The temperature coefficient of delay is less than
500 ppm/deg.C over the operating temperature range of -40 to +85 deg. C.
The module is provided in a 16-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 11
copper leads are tin-lead plated and meet the solderability requirements of MIL-STD-202, Method 208.
