CAUTION: Stress above those listed in “Absolute Maximum Ratings” 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. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
2. θ_JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. θ_JC, the
“case temp” is measured at the center of the exposed metal pad on the package underside. See Tech Brief TB379.
Electrical Specifications Operating Conditions: VCC = 5V, T_A = 0°C to 70°C. Unless Otherwise Specified.
