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

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