The exposed paddle (EPAD) must be soldered to the ground
plane for the 72-lead LFCSP. The EPAD performs as an
electrical and thermal connection to the board.

ESD CAUTION
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
