    Do Fairchild have a site where you can register as a user. Chances are you may be able to get samples for free. I regularly do.

    No sample service to Australia. :-(

    That's unfortunate. Can you find an equivalent from TI or Nat Semi to mention a couple ?

    Ok, they usually charge more, but then they usually have it right away
    also. Delivery is around $5.00 (in Sydney metro at least) or go pick it
    up - you'll probably spend more in fuel. I've never encountered a
    minimum order qty, where they're priced as singles, in over 10 years of
    dealing with them. In fact I've order items that were less in value than
    the shipping with no problems.

    Are you after production quantities or prototypes? If you're
    prototyping, geez what's a few extra bucks?

    Chris.

    I don't have an account. When I use my credit card, the aforementioned
    minimum order value and freight costs apply.
    A friend has a tacho sensor interface board which is converting a
    sinusoidal signal from an alternator to a 5V open collector pulse. The
    output is a little unstable, so I've offered to build him a new board
    from scratch using the above optocoupler and a handful of passive
    support components. Unfortunately his current problem is covered by
    warranty, so he gets his replacement boards for free. This means I'll
    be stuck with troubleshooting someone else's design unless my
    alternative can be built cheaply. $30 is not a lot, but I've already
    told him that it was only going to cost around $5.

    :I'm looking for an optocoupler with Schmitt trigger output, something
    :like Fairchild's H11L1M:

    :I couldn't find it anywhere else but Far-ke-nell:

    :
    :As usual they charge 5 times the going price, plus $10 delivery, plus
    :$10 minimum order, plus GST.

    Franc, you should be able to find MOC5007,8 or 9 quite easily. I have both 5007
    and 9 in Perth if that's where you are.

    Worldwide Electronics in Perth have the H11L1 for $1.65.

    Thanks on both counts. I had already looked for the MOC5007 but
    couldn't find it anywhere.

    I'm now waiting for a response from Worldwide.
