Storage temperature range
(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only. 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 voltages are relative to VSS, except “Cell input differential”.
(3) Negative voltage swings on VC0 in the absolute maximum range can cause unwanted circuit behavior and should be avoided.
