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. ESD on all pins is 2kV except IRDR, which is 1.5kV.
5. _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.
Electrical Specifications V_DD = 3.0V, T_A = +25°C.
