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.
5. θ_JC, “case temperature” location is at the center of the package underside exposed pad. See Tech Brief TB379 for details.
Electrical Specifications These specifications apply for recommended ambient temperature, unless otherwise noted.
Boldface limits apply over the operating temperature range.
