† 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.
NOTE 1: The maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 300 mils,
except for the N package, which has a trace length of zero. For more information, refer to the
