ADuM123x: Does it require external supplies for VDDA and VDDB?

I'm planning to use ADuM1233 in my project. I studied its datasheet today. There is something I'm trying to make clear which is not clearly mentioned in the datasheet. How are the VDDA and VDDB voltages are supplied? Does ADuM123x supply these itself via an on-chip circuit. Or, must the user supply them from outside the chip?

 

One more question I've just remembered: Does this IC have internal shoot through protection? I don't see it in the block diagram. I'm just trying to make sure of it.

 

Please give information on these matters.
