(6) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature of 150°C. Short circuit test is a momentary test. Output short circuit duration is
infinite for V
S
≤ 6V at room temperature and below. For V
S
> 6V, allowable short circuit duration is 1.5 ms.
(7) Slew rate is the slower of the rising and falling slew rates. Connected as a Voltage Follower.
