Heat Sink

NC

No Connect. The metallic back surface of the package is not electrically connected to any part of the circuit.

It can be left floating for optimal electrical isolation between the package handle and the substrate of the die.

It can also be soldered to the application board if improved thermal and/or mechanical stability is desired.

Exposed metal at the corners of the package is connected to this back surface. Allow sufficient clearance

to vias and other components.
