The Digi Key PDF catalog drives me crazy. All the IC parts
are under different sections labeled by manufacturer.
It is real hard to find new part that do better jobs
unless you know the part number.

Their search engine does not help much.

I tried to improve the index and here is what I have so
far. This is a work in progress and will just get you
in the ball park at best.

You need to download their entire 131 meg pdf catalog to use this.
