Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. Ratings at 25°C ambient temperature unless otherwise specified.
2. Derate by 20% for capacitive loads.
