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. These ratings are limiting values above which the serviceability of any
semiconductor device may be impaired.
Nonrecurrent square wave Pulse Width = 8.3 ms, TA = 50°C.
