CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. NOTE #1 θ_JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech
Brief TB379 for details.
2. All voltages are relative to GND, unless otherwise specified.
