(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and 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.
(2) All voltage values are with respect to ANODE, unless otherwise noted.
(3) Temperature and/or supply voltages must be limited to ensure that the maximum dissipation rating is not exceeded.
(4) The package thermal impedance is calculated in accordance with JESD 51-7.
(5) Long-term high-temperature storage and/or use at the absolute maximum ratings may result in a reduction of overall device life. See
http://www.ti.com/ep_quality for additional information on enhanced plastic packaging.
