    Hi ,i'm requesting if i can be guided.
    Since the lm3909 from the datasheet pages is an oscillator /LED flasher i think it can be replaced with 555 timer which still can be used as an oscillator and timer, is it true?If yes how can this cct be replaced with a 555 as in the attached schematic? PLS help
