Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. For guaranteed performance limits and associated test
conditions, see the Electrical Characteristics tables.
Note 2: To minimize power dissipation, low duty cycle pulse testing is used.
Note 3: Power dissipation at TA = 25°C is equal to 1.0W for the 8 lead P DIP package and 625mW for the SO-8 package. For operation at temperatures above
TA = 25°C derate the power dissipation at 10mW/°C.
