Full Military temperature range T2L input and output Output wavetrain can be started in sync with random events 14-pin DIP package (.165 high) Available in frequencies from 2 Mhz to 100 Mhz Output frequencies controlled to within +2% 10 T2L fan-out capacity design notes The military temperature range Thinny DIP Series Square Wave Generator Modules developed by Engineered Components Company have been designed to provide a T2L level square wave output at frequencies from 2 Mhz to 100 Mhz. These generators are both keyable and synchronizable, producing a continuous output train as long as a zero (low) is maintained at the enable input. As long as the enable input is a 1 (high), the output will be a constant 1 (high). Whenever the enable input goes low, the output wavetrain will start in the same sequence with the first low appearing one-half cycle after trigger, and the first positive edge occurring after the period of one cycle. (Note: The 2 low profile TL COMPATIBLE Thinny DIP sO FR RE WAVE OR MODULE output buffer will add one propagation delay to all times). This feature allows the initiation of a timing wavetrain with the origin in synchronization with another event. These Square Wave Generator Modules are of hybrid construc- tion utilizing the proven technologies of active integrated cir- cuitry 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-217 for a 50C ground fixed environment, is in excess of 3 million hours. The TTLSWGM is offered in thirty (30) different frequencies from 2 Mhz to 100 Mhz. Output frequencies are controlled to within +2% and have a temperature coefficient of less than 500 ppm/C over the operating temperature range of 55 to +100C. These Thinny DIP Series modules are packaged in a 14-pin DIP housing, molded of flame-proof Dially| 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. Li engineered components company 3580 Sacramento Drive, P. O.
