Maximum Ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions beyond those
indicated may adversely affect device reliability. Functional operation under absolute maximumrated conditions is not implied. Functional
operation should be restricted to the Recommended Operating Conditions.
1. I
O
absolute maximum rating must be observed.
2. Measured with minimum pad spacing on an FR4 board, using 10 mm X 1 inch, 2 ounce copper trace with no air flow.
3. Tested to EIA/JESD22A114A.
4. Tested to EIA/JESD22A115A.
