Notes:
1. 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 data sheet. Exposure to “Absolute Maximum Rating” conditions for
extended periods may affect device reliability.
2. Due to the limited drive capability, use for input of the same package only.
3. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
4. Thermal performance on QFN packages assumes exposed pad is soldered (or equivalent) to the device most negative potential (GND).
5. The circuit is designed to meet the DC specifications shown in the table after thermal equilibrium has been established.
