    Thanks for your reply guys.

    I think the 555 I.C solution may be the simplest. I have some NE555'
    - I believe they are the CMOS type?

    Is the formula T = 1.14*R*C

    Does the output sink high/low during the timing period?

    Can the output signal be used to drive another I.C?

    Thanks
     
  2. IIRC, NE555 aren't CMOS. Look for something like the ICM7555. And apart
    from allowing much longer timing intervals, the quiescent current is tiny.

    Agreed. NE555 is the normal bipolar version of the IC. As Dave says ICM7555
    is a CMOS
