NOTES
1. DNC = DO NOT CONNECT.
2. IT IS RECOMMENDED THAT THE EXPOSED PAD BE SOLDERED
TO THE GROUND PLANE FOR THE LFCSP PACKAGE. THERE IS
AN INCREASED RELIABILITY OF THE SOLDER JOINTS, AND
THE MAXIMUM THERMAL CAPABILITY OF THE PACKAGE IS
ACHIEVED WITH THE EXPOSED PAD SOLDERED TO THE
CUSTOMER BOARD.

Exposed Pad. It is recommended that the exposed pad be soldered to the ground plane
for the LFCSP package. There is an increased reliability of the solder joints, and the
maximum thermal capability of the package is achieved with the exposed pad soldered
to the customer board.
