DC Electrical Characteristics

DC Chip Level Specifications

Tabl e 9 lists guaranteed maximum and minimum specifications for the entire voltage and temperature ranges.
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.
