Note:
Permanent device damage may occur if Absolute Maximum Ratings are exceeded. Functional
operation should be limited to the Recommended DC Operating Conditions detailed in this data sheet.
Exposure to conditions beyond the operational limits for extended periods of time may affect device reli-
ability.
