Note: Thermal limiting circuitry on chip will shut down the cir-
cuit 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 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.

The 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 pro-
duction units.
