    Hi guys,

    I am new here and I would like to start participate sharing with you
    a very useful pdf-databook catalogs of different components
    of National Semiconductor, Motorola, Fairchild and some others.
    They are especially good when you have no access to the web and urgently need the data.

    They are exellent quality brand made pdfs, not just home made scans.
    The sizes are about 5-30 megs each. Each have 500-1500 pages.

    But I am not sure if this OK to share them. Maybe they are not allowed to
    be spread for free ...

    So, please tell me and if this is not against the forum's rule I
    will be glad to provide the links in apropriate section of the forum.

    Thanks in advance (and sorry for my English). :)

    If there are copyright notices in any of the databooks or catalogs, then they are not allowed to be shared on this site.

    I was not able to find any specific copyright prohibitions.

    Just regular "Copyright(c) and year" for one of them or "All right reserved" for others.

    Those publications are protected.

    Well, that is as specific a copyright prohibition as there is. It
    means that the copyright owner has not allowed anyone else
    any rights, including the right to post the document online.
    To share the catalogs legally, you would need to obtain the
    express written permission of the copyright owner, which is
    not very likely.

    Question: Are these pdf's avaible from the owner? In case of yes, why are you offering this service?

    I have scanned some old datasheets from books but this is a different thing since the are hard to find elsewhere. This was only done as a service from people who needed those datasheets

    No. Maybe they were but not now.
    Anyway, I don't offer them anymore.
    Thanks to all for the clarifications.

    Many manufacturers are doing a dis-service to people trying to locate information for "older" chips by removing the data sheets and reference material from their website all together.

    If you have our older product, please go to hell.

    I recently bought a GPS board made by Motorola and it is a fairly common one circa 1998 where there are thousands of info links from Google linking back to the Motorola website. Guess what, all the data sheets and reference material are gone.

    If it were not for some kind guys who posted the datasheets on their own websites I would have no way to work on the board.

    My hat off to those manufacturers trying hard gradually posting back old data sheets onto their website.

    Would global be the reason for data disappearing. Conventions for just about anything are
    by Invitatiion only, heavy security. We are allowed to buy the toys to play with at home.
    The C.E.O.s take home the money and control the global economy. What will be left for recovery
    when they can afford to give you a new replacement Instead of parts to repair It,even to
    there own service department. I have seen t.v. washer /dryers replaced that needed a
    simple part.

    If we shall take the copyright law in a literal sense. Posting any data sheet as document in this forum is not legal. The only legal action is linking to a site maintained by copyright owner, or a site approved by copyright owner

    I can't recall a single instance in which a complete datasheet was posted here. It may have happened, but usually a link is given or an excerpt is copied and printed with accurate attribution. That falls under the fair use exception and is allowed.

    Some component catalogs you can order and they'll send them to you in the mail. Just like Digi-Key, Allied Electronics, and Mouser Electronics. Go to their websites and they should have a "Catalog" icon that you can click on. I've received several of their catalogs.
