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.
*The maximum package power dissipation must be observed.
1. 60 second maximum above 183°C.
2. −5°C/0°C allowable conditions.
