Note 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.

Note 2: The input and output negative-voltage ratings may be exceeded if the input and output

current ratings are observed.
