If you're pulling the datasheet from the vendor website, you can also skim the list of documentation and see if there are any application notes available for the part.

For more "complicated" parts (e.g. lots of signals, high frequency, high power, etc.), integrating the part into a board design isn't necessarily straightforward. Rather than putting a ton of detail in the datasheet, the vendor will sometimes have an entirely separate document with design guidelines for the part.
