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 with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. For θ_JC, the “case temp” location is taken at the package top center.
Electrical Specifications V_DD = 3.3V, V_SS = 0V, T_A = +25°C, Unless Otherwise Specified.
