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
JA is measured in the natural convection at TA = 25°C on a low effective single layer thermal
conductivity test board of JEDEC 51-3 thermal measurement standard. Pin 2 of SOT-23-5/TSOT-23-5 packages is
the case position for
θ
JC measurement.
Note 3.
The device is not guaranteed to function outside its operating conditions.
