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. Ex-
posure to conditions beyond the operational limits for extended periods of time may affect device reliability.
