    What websites do you use for datasheets?

    The three main ones I use, and that are often cited as sources here on the forums are:

    1. Datasheet Archive

    2. All Datasheets

    3. Datasheet Catalog

    Are there any others, particularly if they are for niche components/systems?

    You can add the address containing most original datasheets from Texas Instruments products (mainly the famous 74LS series):
    http://focus.ti.com

    The link redirects to the TI homepage.

    Octopart is a relatively new site developed by three bright college students that has proved extremely useful:
    http://www.octopart.com
    Datasheets, vendors, even stock and availability show up on this free site. Well worth the bookmark overhead.

    National Semiconductor is here:
    http://www.national.com/
    Besides having complete documentation for their products, they also have a great many Application Notes and other technical resources.

    NTE Inc. is here:
    http://www.nteinc.com/

    While their datasheets are abbreviated and their cross-reference works only one way (competitor part to NTE part) - it's still useful. Some discontinued semiconductor items may be only available via NTE - if that is the case, I hope you have a deep wallet.

    Googling for the standard part number usually yields good results. But, as SgtWookie noted, there are manufacturers that don't provide enough information in their datasheets.

    hi,

    i would like to add www.topeway.com

    TopeWay is a vertical search engine for Electronic Datasheet.
    Google search results customized by TopeWay using Google Co-op.

    Hello to the Group,

    I'm looking for the datasheets for these two transistors and if any one could recommend substitutes.

    thanks,
    Jon:)

    A service I often use is http://www.digchip.com/ which has a good part number search engine and instant free access to datasheets

    Supplyframe has datasheets and links to the manufacturers and inventory levels.

    A paid-for service I've used in the past: Partminer. Not sure how much it costs, b/c I went through the company's plan, but a nice feature I discovered is that if the part number doesn't exist in their database, you can add it and they will go research the datasheet for you.

    Now we've switched to 4DOnline, which is a subset of IHS. It's a Java-based website, and I don't like it as much. But it does okay.

    Hello,

    A helpfull resource of datasheets of all kinds (IC's Transistors Optoelectrinics etc.) is:
    http://www.icmaster.com
    You have to register freely, and have access to a lot off datasheets off all manufacturers.

    Greetings,
    Bertus
