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.

Note 2.



JA is measured in the natural convection at T

A=25

oC on a low effective thermal conductivity test board (Single layout,

1S) of JEDEC 51-3 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.
