(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 supply voltages have to be supplied simultaneously.

(3)

The input and output negative voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
