VCC supply input
Ground input
There is an internal electrical connection between the exposed thermal pad
and VSS pin of the device. The exposed thermal pad must be connected to the
same potential as the Vss pin on the printed circuit board. Do not use the
thermal pad as the primary ground input for the device. VSS pin must be
connected to ground at all times.
