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. _JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See TB379.
5. For _JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications Recommended operating conditions, V_CC = 3.3V, unless otherwise specified. Boldface limits apply across the
operating temperature range -40°C to +85°C.
