Note:

1.

Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for

stress ratings. 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 for extended periods may

remain possibility to affect device reliability.

2.

Devices are ESD sensitive. Handing precaution recommended..

3.

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

4.

Guaranteed by design.

5.

Auto Recovery Type.
