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. θ_JAis measured in natural convection at T_A= 25°C on a high-effective thermal conductivity four-layer test board of

JEDEC 51-7 thermal measurement standard. The measurement case position of θ_JCis on the exposed pad of

the package.

Note 3. Devices are ESDsensitive. Handling precaution is recommended.

Note 4. The device is not guaranteed to function outside its operating conditions.

Note 5. Guarantee by design.
