Space Saver FAST TTL Fast Recovery Pulse Generator The Space Saver FAST TTL Fast Recovery Pulse Generators manufactured by Engineered Components Company are designed to provide a precise output pulse width when triggered by variable pulse width inputs. These pulse generators provide a stable positive (+), as well as negative(-), output pulse of the specified width for each rising edge of the input pulse. The input pulse must be low for a minimum of 10 ns before rising to a high for a minimum of 10ns. No output pulse occurs for each falling edge of the input pulse. Maximum input pulse repetition rates are shown in the table below. 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 3 million hours. The temperature coefficient of delay is less than +/-100 ppm/deg.C over the operating temperature range of 0 to +70 deg. C. The module is provided in a 8-pin Space Saver 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 5 copper leads are tin-lead plated and meet the solderability requirements of MIL-STD-202, Method 208.
