Notes:

2. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied

at conditions other than those detailed in the operational sections of this datasheet. Exposure to absolute maximum rating conditions for extended

periods may affect device reliability.

3. The datasheet limits are not guaranteed if the device is operated beyond the operating ratings.

4. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the device’s most negative potential on the PCB.

5. The circuit is designed to meet the AC and DC specifications shown in the above tables after thermal equilibrium has been established.
