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. 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 θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications Operating Conditions: V_CC = 5V, V_CC12 = 12V, T_A = 0°C to 70°C, Unless Otherwise Specified
