    hello guys,

    I usually find the parts I am looking for on digikey web site. I have
    not order from there for a long time. But have they decrease
    selectivity of products. I was looking for low pass filter chip.ie
    MAX7480EPA, but it is non stock and minimum of 50.. and that is the
    only with 2k fc. also I was looking for dtmf dialer, and they are now
    obsolete. Is it just my luck or are they not keeping as many parts as
    before ?

    Maxim is pretty famous for rolling out ICs, running them for a few
    yeras, and then limiting their availability. But today is your lucky
    day on that one. The MAX7480EPA+ (the + stands for lead-free and RoHS
    qualified) is available and in stock from both DigiKey and Maxim
    directly. Try it.

    If you're having problems with availability on a part, always check
    with the manufacturer's website for further information.

    Obsolete means obsolete. The distributors don't have anything to do
    with this. But without a part number, a cross-reference isn't
    possible. Most DTMF dialers are obsolete.

    Good luck
    Chris

    yes I know about the MAX7480EPA+, it is just that I do not want a
    minimum of 50...

    k
    just 5 would be enough

    Newark has them in stock, no minimum quantity, 1-24 @$5.67.

    I'm surprised that the search engine at http://www.findchips.com is
    not better known. It doesn't support a parametric search but once you
    know the part number you're looking for, it can be quite handy.
     
  5. Hey, that's REALLY handy.
    Thanks for the link.
    It's earned a place on my browser toolbar.

    These days, it's not worth it, when practically anyone can whip up
    a DTMF tone genny with just about any uP or FPGA/CPLD chip and a few
    discretes. (of course, you'd need the development kit, but I guess
    they can be found for $20.00 ~ $50.00 .)

    Cheers!

    Several DTMF ICs are coming up with a google search for 'DTMF dialer ic'

    If you get into a bind, let me know, I have several...I can part with one.
