(5) 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.
(6) Short circuit test is a momentary test. Output short circuit duration is infinite for V
S
≤ ±2.5V, at room temperature and below. For V
S
>
±2.5V, allowable short circuit duration is 1.5ms.
