The 'Pin-Out' section has pin connection and package details for connectors and components. Each article includes pin assignments, applications, assembly instructions and more, and can be accessed from the main menu or the link below.
Unfortunately we cannot provide semiconductor datasheets, but try searching on the Farnell or RS web sites. They both have data libraries with datasheets to download in PDF format. Either can be accessed without needing to register - simply search for the part you want and click the datasheet link / icon.
If you have any info. you feel should be in this section, or any other comments, then please contact me.
