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.

OPERATING RANGES

The Operating Ranges define those limits between which the

functionality of the device is guaranteed.

* Functionality of the device from 0

°C to +70°C is guaranteed

by production testing.
