(7) The short circuit test is a momentary test which applies to both single-supply and split-supply operation. Continuous short circuit
operation at elevated ambient temperature can exceed the maximum allowable junction temperature of 150°C. Positive number (+) is
sourcing, negative number (-) is sinking.
(8) Enable voltage is referred to V- (negative supply voltage).
(9) Slew Rate is the average of the rising and falling edges.
