Notes

3.Higher storage temperatures reduce data retention time. Recommended storage temperature is +25°C ± 25°C. Extended duration storage temperatures above 85oC degrade reliability.

4.Human Body Model ESD.

5.According to JESD78 standard.

6.The temperature rise from ambient to junction is package specific. See Package Handling on page 25. The user must limit the power consumption to comply with this requirement.
