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 “rec-
ommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may
affect device reliability.
2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
