NOTES A. The shaded terminals are used for electrical and thermal connections to the ground plane. All the shaded terminals need to be electrical
connected to ground. No connect (NC) terminals still need a pad and trace.
B. The thermal pad of the DRB and DGN packages must be electrically and thermally connected to a ground plane.
