(1) Solder the exposed thermal pad (RTW package) to a heat-spreading power or ground plane. This pad is electrically isolated from the
die, but must be connected to a power or ground plane and not floated.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Staying below this ± supply turn-on edge rate ensures that the edge-triggered ESD absorption device across the supply pins remains
off.
(3) Long-term continuous current for electro-migration limits.
