*1. The NC pin is electrically open.

The NC pin can be connected to the VIN pin or the VSS pin.

*1.

Connect the exposed thermal

die pad at shadowed area to

the board, and set electric

potential open or VSS.

However, do not use it as the

function of electrode.

*2. Be careful of the contact with

other wires because the pinch

lead has the same electric

potential as VSS.
