NOTES
1. NC = NO CONNECT. DO NOT CONNECT TO THIS PIN.
2. EXPOSED PAD. THE EXPOSED PAD 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 EXPOSED PAD. ALLOW SUFFICIENT CLEARANCE TO VIAS AND OTHER COMPONENTS.

EPAD
Exposed Pad. The exposed pad 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 exposed pad. Allow sufficient clearance to vias and other components.
