(5) Short circuit test is a momentary test. See Note 6.
(6) Output short circuit duration is infinite for V

≤ 6V at room temperature and below. For V
S
> 6V, allowable short circuit duration is 1.5ms.
(7) Slew rate is the slower of the rising and falling slew rates. Connected as a Voltage Follower.
