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.

Refer to Package Dissipation Table
(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, except differential I/O bus voltages, are with respect to network ground terminal.
