Whats the application difference between sinking and sourcing inputs?
I know that sinking inputs just provide a path to to ground for current, and sourcing inputs provide a path to the + end.
I do not understand the application benefits and negatives of sourcing/sinking. When would I want a sourcing input and when would I want a sinking input?

Hi,
Obviously it depends on the outputs you connet to the input.
Also if the outputs (also switches) have a common '+' or common '-' connection.

If you have NPN or PNP type devices in your application, choosing of sinking or sourcing inputs from the start would get your job easier.
