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. 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. For JC, the “case temp” location is the center of the exposed metal pad on the package underside.

Electrical Specifications

These specifications apply for TA = -10°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,

-10°C to +100°C.
