    Hi all,

    I need a one-shot monostable vibrator that delivers a positive pulse that is about 5 seconds long (+/- about a second). I have a bunch of CD4528s and they seem to fit the bill but in the data sheet I could not find a value for the maximum pulse width that it can deliver. I can certainly calculate a resistor/capacitor combo that gives me the required pulse width but I was wondering if there is a maximum value for this component that I may be exceeding.

    Thanks!

    Kevin

    P.S. Data sheet attached

    There is no maximum. Make C as large as you wish.
