NOTE:
Stress greater than those listed under "Absolute Maximum Ratings" may cause per ma nent damage to the device. This is a stress rating only and
func tion al op er a tion of the device at these or any other conditions greater than those in di cat ed in the operational sections of this specifi cation is not
implied. Exposure to ab so lute maximum rating con di tions for extended periods may affect reliability.
NOTE:
Refer to Application Note “PBGA Thermal Resistance Correlation” at www.wedc.com in the application notes section for modeling conditions.
