*1. Connect the heat sink of backside at shadowed area to the board, and set electric potential GND.
However, do not use it as the function of electrode.
*2. The NC pin is electrically open.
Therefore, leave it open or connect it to the VDD pin or the VSS pin.
Caution Do not place a wiring on the backside of the package.
