Hello colleagues, we at the FED in Germany have a problem to interprete the term "one-shot". It is used in IPC-D-275 in the testability design checklist. The complete sentence is: Avoid one-shots; if used, route their signals to the edge connector. Could somebody please try to give a definition for "one-shot"?
