Note 1.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those

indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating

conditions may affect device reliability.

Note 2.

θJA is measured under natural convection (still air) at TA = 25°C with the component mounted on a high effective-

thermal-conductivity four-layer test board on a JEDEC 51-7 thermal measurement standard.

θJC is measured at the

exposed pad of the package.

Note 3.

Devices are ESD sensitive. Handling precaution is recommended.

Note 4.

The device is not guaranteed to function outside its operating conditions.
