> 6V,
allowable short circuit duration is 1.5ms.
(6) Slew rate is the slower of the rising and falling slew rates. Connected as a Voltage Follower.

(1) Typical Values represent the most likely parametric norm.
(2) All limits are guaranteed by testing or statistical analysis.
(3) Offset voltage average drift determined by dividing the change in VOS at temperature extremes into the total temperature change.
(4) Positive current corresponds to current flowing into the device.
