FAST TTL Gated Square Wave Generator
The FAST TTL Gated Square Wave Generators manufactured by Engineered Components Company are designed to provide a square wave output at
a given frequency. These generators are both keyable and synchronizable, producing a continuous output train as long as a TTL “low” is applied
to the input. With a TTL “high” applied to the input, output 1 will produce a constant “high” and output 2 will produce a constant “low”. When
the input switches to “low”, output 2 goes “high” immediately. Output 1 and output 2 both go low after one half-cycle and then run in phase as a
continuous square wave output. When the input switches back to “high”, output 2 goes “low” immediately and output 1 goes “high” one
half-cycle later.
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 5 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 5 copper leads are tin-lead plated and meet the solderability requirements of
MIL-STD-202, Method 208.
