(3)

Slew rate is the average of the rising and falling slew rates.

(4)

Offset voltage average drift determined by dividing the change in VOS at temperature extremes by the total temperature change.

(5)

Positive current corresponds to current flowing into the device.

(6)

Short circuit test is a momentary test. See Note 7.

(7)

Output short circuit duration is infinite for VS < 6V at room temperature and below. For VS > 6V, allowable short circuit duration is 1.5ms.
