result in failures not covered by warranty.

NOTES:

1.

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.

2. For

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

Electrical Specifications

VDD = 5V, TA = -40°C to +100°C, unless otherwise specified.
