Note: Thermal limiting circuitry on chip will shut down the

circuit at a junction temperature of about 165°C. The device

should never be exposed to this temperature. Operation

above 145°C junction temperature may degrade device

reliability. See the SLIC Packaging Considerations section 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 define those limits over which the

functionality of the device is guaranteed by production

testing.

* Functionality of the device from 0°C to +70°C is guaranteed

by production testing. Performance from –40°C to +85°C is

guaranteed by characterization and periodic sampling of

production units.
