An RF-coupled digital isolator includes a first leadframe portion and a second leadframe portion, electrically isolated from one another. The first leadframe portion includes a first main body and a first finger. The second leadframe portion includes a second main body and a second finger. The first main body is connected to a first ground, and the second main body is connected to a second ground that is electrically isolated from the first ground. The first finger and the second finger are electrically isolated from one another, e.g., by a plastic molding compound that forms a package for the digital isolator. The first finger acts as a primary of a transformer, and the second finger acts as a secondary of a transformer, when an RF signal drives to the first finger. The first finger and the second finger can be substantially parallel or anti-parallel to one another.
