(1) The Electrical Characteristics tables list verified 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
verified.
(2) Current into device pins is defined as positive. Current out of a device pin is defined as negative. Voltages are referenced to ground
except V_OD, ΔV_OD, V_TH and V_TL which are differential voltages.
(3) Typical values represent most likely parametric norms at 1.8V or 3.3V, T_A = +25°C, and at the Recommended Operation Conditions at
the time of product characterization and are not verified.
