Asking a question

I like getting email, but I already get a lot of it, so to save you and me time please check the next list with hints. It will often give you the standard answer that you would get from me anyway (and only after a couple of days).

Do you want:

If you want a datasheet or databook

I haven't got serious facilities to provide datasheets or databooks or copies of them.

Try this:

Other sites with a lot of chip data are:

www.chipinfo.ru/ Site is in Russian, but the chip data is mostly in English. They mirror the Chipdir in Moscov.
www.icmaster.com/ Lots of data but you need to register first!
cmpmedia.globalspec.com/ Lots of data.
www.semidex.com/ Only for memory chips.
www.freetradezone.com/ You need to register first.

If you want a description or the manufacturer of a strange chip.

Always check the
numerical and prefix listings in the Chipdir first.
Then subscribe to the Chipdir Mailing List and ask there and mention as much as possible of:

I read that Chipdir Mailing List too. Make sure the subject line is something like 'looking for description of SN74LS00'.

You can also check other WWW sites like cmpmedia.globalspec.com/. See the main page for more of them.

If you want to buy some chips.

What are you looking for:

If you want a serious amount of scarce chips

(For example for production purposes). Any amount of chips (of a single kind) that you're willing to pay say $200 or more ($100 when you're in the USA...) for, is a serious amount.

Use this form to look for the chips in the IC* Source database and later press the RFQ (Request For Quote) button to get a quote later via email.

If you want non-scarce chips

Generally it's much cheaper to locate your local distributor and ask him. He can also provide you with other services like data sheets and stocking chips in your behalf etc. He can also ask the manufacturer to produce extra chips in the next batch for you etc.
Most distributors don't like small orders. Try to order them from mail order companies like Digikey, Farnell and Mouser:

You can also ask if your local electronics retailer can order them for you. He can combine this with his usual orders which saves a lot of costs for you and the distributor. Some universities also have a central facility for ordering stuff.
When you're looking for small amounts of PC parts like CPU
*'s, SIMM's and cache chips: Try the local PC shops or visit a local PC fair. They are usually much better at these things than chip distributors/dealers and the margins in that market segment are very low.

If you want small amounts of scarce chips

This a serious problem, because most people will find using the chip brokerage market for this purpose too expensive ($100 to $400).
When you want to repair something, please consider first if it is worth that much money.
Never use scarce chips for new designs! (Not even if you already have them in your possesion.)
Please consider that asking others via the Internet to find these chips (or their datasheets) may seem to cost nothing (to you), but others will have to spend time and thus money on it.
Having said this:

If you want something added to the Chipdir

Unless you want to add
company data, please use this form.

If you want something else

Any other tips, questions, suggestions, stories, encouragements?
That's great, email
me!
