(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 are with respect to network ground terminal.
