ELECTROSTATIC DISCHARGE (ESD) PROTECTION
ABSOLUTE MAXIMUM RATINGS

RECOMMENDED OPERATING CONDITIONS
SGLS371 – JANUARY 2007
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.
