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 RATlNG 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 values assume exposed pad is soldered (or equivalent) to the device's most negative potential on the PCB.
4.
This circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
5.
