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. θJA 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. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications
These specifications apply for TA = -40°C to +100°C, unless otherwise stated. All typical specifications
TA = +25°C, VDD = 5V, PVCC = 5V. Boldface limits apply over the operating temperature range,
-40°C to +100°C.
