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, and R_L = 100Ω (or as
specified) tied to V⁺/2. Boldface limits apply at the temperature extremes.

(5) Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
(6) Positive current corresponds to current flowing into the device.
(7) Short circuit test is a momentary test. See Note 6 under Absolute Maximum Ratings.
