Great place to find Data Sheets.

This site is where Digi-key has its data sheet for most of its items.
Great place to get the data sheets you need for the parts you wish to use.
Onsemi data sheet site.
Also if you want to know about different parts available is to use digi-key.com or digi-key.ca to see what is available. I personal use digi-key for all my development/prototype projects as they have the data sheets and dimensions of the parts, this allows me to lay-out/build my PCB board before I get my parts.
