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