CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact

product reliability and result in failures not covered by warranty.

NOTES:

4. θ JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach”

features. See Tech Brief TB379.

5. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside.

6. Parameters with TYP limits are not production tested, unless otherwise specified.

7. Parameters are 100% tested for internal IC prior to module assembly.

Electrical Specifications

Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified.

Temperature limits established by characterization and are not production tested. Boldface

limits apply over the operating temperature range, -40°C to +85°C.
