Electrical Specifications
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device.
These are absolute stress ratings only. Functional operation of the device in not implied at these
or any other conditions in excess of those given in the operational sections of the IPS. Exposure
to absolute maximum ratings for extended periods can adversely affect device reliability.
