debouncer

Various microprocessor circuits place particular requirements upon the duration of certain control signals. If these signals are generated by 7 r _. 1 manually operating a switch or key u ,- J--,f--....-~ (e.g. reset and interrupt keys), then the conventional debounce circuit consisting of an RS flip-flop is not always foolproof, since there is always the chance that the key will be released prematurely.
