5V Electrical Characteristics (continued)
Unless otherwise specified, all limits guaranteed for at T_J = 25°C, V⁺ = 5V, V^− = 0V, V_CM = V_O = V⁺/2, V_ID (input differential
voltage) as noted (where applicable) and R_L = 2kΩ to V⁺/2. Boldface limits apply at the temperature extremes.

(3) Slew rate is the average of the rising and falling slew rates.
(4) Offset voltage average drift determined by dividing the change in V_OS at temperature extremes by the total temperature change.
(5) Positive current corresponds to current flowing into the device.
(6) Short circuit test is a momentary test. See Note 7.
(7) Output short circuit duration is infinite for V_S < 6V at room temperature and below. For V_S > 6V, allowable short circuit duration is 1.5ms.
