Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.

–40°C to 85°C operating temperature range are assured by design,
characterization and correlation with statistical process controls.

Note 4: Failure to solder the exposed backside of the package to a PCB
ground plane will result in a thermal resistance much higher than 80°C/W.
