*Notice: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at these or any other condition
beyond those indicated in the operational sections of this specification is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Warning: This product package includes an integrated (exposed thermal pad) heatsink that must be soldered to the
printed circuit board; failure to adequately heatsink this product will affect device reliability.
