CAUTION: Stress above those listed in âAbsolute Maximum Ratingsâ may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational section of this specification is not implied.
NOTES:
1. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
2. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with âdirect attachâ features. See
Tech Brief TB379 for details.
3. θJC, "case temperature" location is at the center of the exposed metal pad on the package underside.
Electrical Specifications Operating Conditions: VCC = 5V, TA = -40°C to 85°C. Unless Otherwise Specified.
