(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) Typical values represent most likely parametric norms at V
DD
= 3.3V, Ta = +25 degC, and at the Recommended Operation Conditions at
the time of product characterization and are not guaranteed.
(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, ΔVOD, VTH and VTL which are differential voltages.
