Maximum power dissipation, T
Note: Thermal limiting circuitry on chip will shut down the cir-
cuit at a junction temperature of about 160°C. The device
should never be exposed to this temperature. Operation
above 145°C junction temperature may degrade device reli-
ability. See the SLIC Packaging Considerations for more in-
formation.

Operating ranges define those limits over which the function-
ality 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.
