AC Electrical Characteristics
Unless otherwise specified, all limits ensured for T_J = 25°C, V⁺ = 5V, V^− = 0V, V_CM = V_O = V⁺/2. Boldface limits apply at the
temperature extreme.

(1) Typical Values represent the most likely parametric norm.
(2) All limits are specified by testing or statistical analysis.
(3) C_L inlcudes the probe and jig capacitance. The rise time, fall time and propagation delays are measured with a 2V input step.
