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:
5. ABS max voltage rating is defined as the voltage applied for a lifetime average duty cycle above 6V of 1%.
6.

7. Fo r
JC
, the “case temp” location is the center of the exposed metal pad on the package underside.
8. Extended operation at these conditions may compromise reliability. Exceeding these limits will result in damage. Recommended operating conditions
define limits where specifications are guaranteed.
9. Electromigration specification defined as lifetime average junction temperature of +110°C where max rated DC current = lifetime average current.
