Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Measured with minimum pad spacing on an FR4 board, using 10 mm−by−1 inch, 20 ounce copper trace with no air flow.
2. IO absolute maximum rating must observed.
3. Tested to EIA/JESD22−A114−A.
4. Tested to EIA/JESD22−A115−A.
5. Tested to EIA/JESD78.
