* It should be connected the VSS pin (No. 2 and 5) to the GND pin.

* If the dissipation pad needs to be connected to other pins, it should be

connected to the GND pin.

* Please refer to pattern layout page for the connecting to PCB.

* The ”-G” suffix indicates that the products are Halogen and Antimony free as well as being fully RoHS compliant.
