NOTE: Pb-free PDIPs can be used for through hole wave solder processing
only. They are not intended for use in Reflow solder processing
applications.
CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
6. Input voltages may exceed the supply voltages provided the input current is limited to ±100µA.
7. _JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
