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. ESD on all pins is 2kV, except for IRDR, which is 1.5kV.
Electrical Specifications V_DD = 3.0V, T_A = +25°C, R_EXT = 499kΩ 1% tolerance. Boldface limits apply over the operating
temperature range, -40°C to +85°C.
