SLVS789A – NOVEMBER 2007 – REVISED FEBRUARY 2008

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.

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.

The JEDEC high-K (2s2p) board used to derive this data was a 3in

×3in, multilayer board with 1-ounce internal power and ground planes

and 2-ounce copper traces on top and bottom of the board.
