Notes:
2. Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only.
Functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
3. All voltage values are with respect ground.
4. Maximum power dissipation is a function of T (max), θ , and T . The maximum allowable power dissipation at any allowable ambient temperature

is P = (T (max) – T )/θ . Operating at the absolute maximum T of 150°C can affect reliability.
