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. The heat generated must be less than the thermal conductivity from

Junction-to-Ambient: dPD/dTJ < 1/RqJA.
