For Recommended soldering conditions see Tech Brief TB389.
CAUTION: Stresses 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 sections of this specification is not implied.
NOTE:
1. 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. JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. JC, the
“case temp” is measured at the center of the exposed metal pad on the package underside. See Tech Brief TB379.
Electrical Specifications Recommended Operating Conditions with Vcc = 5V, unless otherwise noted.
