5V Electrical Characteristics⁽¹⁾
Unless otherwise specified, all limits are specified for T_A = 25°C, V⁺ = 5V, V^− = 0V, V_CM = V⁺/2, and R_L > 10 kΩ to V⁺/2.
Boldface limits apply at the temperature extremes.

(1) Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very
limited self-heating of the device such that T_J = T_A. Parametric performance is indicated in the electrical tables under conditions of
internal self-heating where T_J > T_A.
(2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlations using the
Statistical Quality Control (SQC) method.
(3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested on shipped production material.
(4) This parameter is specified by design and/or characterization and is not tested in production.
(5) Positive current corresponds to current flowing into the device.
(6) The maximum power dissipation is a function of T_J(MAX), θ_JA. The maximum allowable power dissipation at any ambient temperature is
P_D = (T_J(MAX) – T_A)/ θ_JA. All numbers apply for packages soldered directly onto a PC Board.
(7) The short circuit test is a momentary test.
(8) The number specified is the slower of positive and negative slew rates.
