■PIN CONFIGURATION

* Please short the VSS pin (No. 2 and 5).

* The dissipation pad for the USP-6C

package

should

solder-plated

recommended mount pattern and metal

masking so as to enhance mounting strength

and heat release. If the pad needs to be

connected to other pins, it should be

connected to the VSS (No. 5) pin.
