(4) Offset Voltage average drift determined by dividing the change in V
OS
at temperature extremes into the total temperature change.
(5) Positive current corresponds to current flowing into the device.
(6) Short circuit test is a momentary test. See next note.
(7) Output short circuit duration is infinite for V
S
< 6V at room temperature and below. For V
S
> 6V, allowable short circuit duration is 1.5ms.
(8) Positive current corresponds to current flowing into the device.
