Notes
10. Higher storage temperatures reduce data retention time. Recommended storage temperature is +25 °C ± 25 °C. Extended duration storage temperatures above 85 °C
degrade reliability.
11. The temperature rise from ambient to junction is package specific. See Package Handling on page 31. The user must limit the power consumption to comply with this
requirement.
