Notes:
1. Permanent device damage may occur if the ratings in “Absolute Maximum Ratings” section 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 data sheet. Exposure to absolute maximum ratings
conditions for extended periods may affect device reliability.
2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
3. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the device’s most negative potential (GND) on the PCB. ψJB uses
4-layer θJA in still air unless otherwise stated.
4. The specifications shown are valid after thermal equilibrium has been established.
5. 100K circuits are designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
