Note 1.

Stresses beyond those listed “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.

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

Note 3.

Devices are ESD sensitive. Handling precaution is recommended.

Note 4.

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

Note 5.

Specification is guaranteed by design and/or correlation with statistical process control.
