reliability and result in failures not covered by warranty.
ΝΟΤΕΣ:
5. 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.
6. θ 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 .
7. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications All typical specifications T A = +25°C, VCC = 5V. Boldface limits apply over the operating temperature range,
-40°C to +100°C, unless otherwise stated.
