Other sites where you can search on chip number Very good! Registration is needed in advance. Will be closed spring 2002. Registration is needed before you can download datasheets. Chips can sometimes be ordered via Arrow/Avnet. In Japanese only.

For more data about the above WWW sites and for more information sites. Do a search at 20+ distributors at once! Do a search for scarce chips at many brokers at once!

To get chips listed

When you're the webmaster/database manager of an IC* manufacturer and you'd like to get your IC*'s listed on sites like these (including the ICMaster) but don't want to deal with all sites separately, a couple of us are trying to set up a system whereby the IC* manufacturers just put a comma seperated value's (.csv) file on their site with all of their data and we all read that regurarly and work the data into our databases of chips. Please visit for more details. One of the manufacturers already cooperating is ON Semiconductor (formerly part of Motorola).
