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 θJA 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.
