SNVS681D – NOVEMBER 2010 – REVISED MAY 2013

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.

Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is specified and do not imply ensured performance limits. For specified performance limits and associated

test conditions, see the Electrical Characteristics table. All voltages are with respect to the potential at the GND pin, unless otherwise

specified.
