Catalog of all electronic and semiconductor component datasheets

DSP Innovations has recently launched a FREE data sheet search site. The site, www.datasheetpro.com , enables component and design engineers to easily find electronic and semiconductor datasheets necessary for their projects. Please try
out the service and provide your feedback to support -at- datasheetpro [dot] com.
Additionally, the site will allow manufacturers to upload their newest datasheets
and cross references for search. Please see www.datasheetpro.com/services.php for
details.

hmm... at first i thought this was spam, but the site does actually give you easy access to datasheets. its cluttered with ads and doesnt have many parts. a search for atmega168 didnt turn anything up :-/

personally, i'll stick with octopart.com

I have to admit, I always use Octopart, it's a search that seems as powerful as Google (or do they use a Google API?) And it gives you helpful links to both datasheets, manufacturers and pricing. Not to mention, a pretty picture!
