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.

1. Ratings at 25

°C ambient temperature unless otherwise specified.

2. Derate by 20% for capacitive loads.
