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.
