Thats your answer, grab the data sheets. ;-)


That's what I resort to, although it really would be nice if there was a
one stop shop of package drawings or dimensions. There are so many
different packages now that I can't keep track of them all.


For example this datasheet has 5 different package drawings that it calls
"Small Outline Package", all with different dimensions:

Isn't the idea of a package "name" supposed be a single identity including
dimensions (differing, of course, in length, to accommodate different pin
counts)?

From the same manufacturer, no less...

Thanks,
