Full Military temperature range T2L input and output Pulse width detection stable and precise 14-pin DIP package (.165 high) Available in pulse widths from 5 to 500ns 8 T2L fan-out capacity design notes The military temperature range Thinny DIP SeriesLogic Noise Filter Modules developed by Engineered Components Company have been designed for use in T2L systems employing data pulses of either a fixed width or a minimum width. The filter module will produce a 1 at the output, without significant change in width, only when a '1" appears at the input for greater than the specified pulse width; all shorter pulses will be suppressed. This operation will effectively eliminate sources of stray noise pulses and should prove particularly effective in eliminating transients created by crosstalk from leading edges of fast rise time pulses, 2 low profile TL COMPATIBLE Thinny DIP LOGIC NOISE FILTER MODULE The TTLNFM is offered in 24 pulse widths from 5ns to 500ns, for optimum noise pulse rejection in various systems. Tolerance on pulse width recognition is maintained as shown in the accompanying part number table, when tested under the Test Conditions shown. Temperature coefficient is less than +800 ppm/C over the operating temperature range of 55 to +100C. These Noise Filter Modules are of hybrid construction utilizing the proven technologies of active integrated circuitry and of passive networks utilizing capacitive, inductive and resistive elements. The ICs utilized in these modules are burned-in to Level B of MIL-STD-883 to ensure a high MTBF. The MTBF on these modules, when calculated per MIL-HDBK-217B for a 50C ground fixed environment, is in excess of 3.5 million hours. These Thinny DIP Series modules are packaged in a 14-pin DIP housing, molded of flame-proof Diallyl Phthalate per MIL-M- 14, Type SDG-F, and are fully encapsulated in epoxy resin. Flat metal leads meet the solderability requirements of MIL-STD-202, Method 208. i engineered components company 3580 Sacramento Drive, P. O.
