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. Devices are ESD sensitive. Handling precaution recommended.

Note 3. The device is not guaranteed to function outside its operating conditions.

Note 4.

θJA is measured in the natural convection at TA = 25°C on a low effective thermal conductivity single layer test board of

JEDEC 51-3 thermal measurement standard.

Note 5. The FLAG delay time is input voltage dependent, see

“ Typical Operating Characteristics” graph for further details.
