5V Electrical Characteristics
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.

(1) All limits are guaranteed by testing or statistical analysis.
(2) Typical values represent the most likely parametric norm.
(3) Slew rate is the "worst case" of the rising and falling slew rates.
(4) Output Swing not limited by Slew Rate limit.
