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:
1. _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.
2. For _JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications V_DD = 5V, T_A = -40°C to +100°C, unless otherwise specified.
