(1) The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as
otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and
are not guaranteed.
(2) Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground
except V_OD and ΔV_OD.
(3) Typical values represent most likely parametric norms for V_DD = +3.3V and T_A = +25°C, and at the Recommended Operation Conditions
at the time of product characterization and are not guaranteed.
(4) C_L includes fixture capacitance and C_D includes probe capacitance.
(5) Specification is guaranteed by characterization and is not tested in production.
(6) Output short circuit current (I_OS) is specified as magnitude only, minus sign indicates direction only.
