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:

4. ACSET may be operated 1V below GND if the current through ACSET is limited to less than 1mA.
