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 device may occur, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the s or other conditions beyond
those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating Conditionsindicate conditions
at which the device is functional and the device should not be operated beyond such conditions. All voltages are measured with respect
to the ground pin, unless otherwise specified.
