These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to GND.
(3) Do not apply voltage to pin.

(1) Tested per JEDEC JESD51, natural convection. The definitions of high-k and low-k are per JESD 51-7and JESD 51-3.
(2) Low-k (2 signal - no plane, 3-inch by 3-inch board, 0.062-inch thick, 1-oz copper) test board with the pad soldered, and an additional
0.12 inch. 2 of top-side copper added to the pad.
(3) High-k is a (2 signal – 2 plane) test board with the pad soldered.
(4) The best case thermal resistance is obtained using the recommendations per SLMA002A (2 signal - 2 plane with the pad connected to
the plane).
