Do you know finchips web sites? In this web site you can search more that 20 semiconductors distributers web sites, simultaneously. So you can see the availability of a part or compare the prices.
But I need a similar search engine that searches semiconductors manufacturers web sites (not distributers). For examples I want to search ST, Motorola, Fairchilds, TI, ADI, NXP, AAT, **broken link removed** web sites simultaneously to find today who is manufacturing a special part number?
