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.

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 “direct attach” features. See

Tech Brief TB379.

3. For

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

Electrical Specifications

Operating Conditions: VCC = 5V or ICC < 25mA (Note 3), TJ = 0°C to 105°C.
