PIN CONFIGURATIONS AND FUNCTION DESCRIPTIONS

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.
