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.
NOTES:
6. 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.
7. θ_JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. θ_JC, the
“case temp” is measured at the center of the exposed metal pad on the package underside. See Tech Brief TB379.
8. All voltages are with respect to GND.
Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to Block Diagram and Typical Application
schematic. V_CC = +5.0V ±10%, T_A = -40 to 85°C (Note 9), Typical values are at T_A = 25°C
