Pin Description
Absolute Maximum Rating
Stresses exceeding the absolute maximum rating may damage the device. The device may not function or be operable above the
recommended operating conditions and stressing these parts to these levels is not recommended. In addition, extended exposure to
stresses above the recommended operating conditions may affect the device reliability. The absolute maximum rating are stress rat-
ings only.
Note 1: Package power dissipation based on 4 layer, 2 square inch, 2 oz. copper pad. R
