NOTES
1. DNC = DO NOT CONNECT. DO NOT CONNECT TO THIS PIN.
2. IT IS RECOMMENDED THAT THE EXPOSED PADDLE 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 PADDLE SOLDERED TO THE CUSTOMER BOARD.

EPAD
Exposed Pad. It is recommended that the exposed paddle 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 paddle
soldered to the customer board.
