Thermal Data:
Note:
circuit at a junction temperature of about 165°C . The device
should never see this temperature and operation above 145°C
junction temperature may degrade device reliability. See the
SLIC Packaging Considerations for more information.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent device failure. Functionality at or above
these limits is not implied. Exposure to Absolute Maximum
Ratings for extended periods may affect device reliability.
