(1) 2.7-V and 4.5-V DC and AC Electrical Characteristics 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 not ensured in the
2.7-V and 4.5-V DC and AC Electrical Characteristics under conditions of internal self-heating where T_J > T_A.
(2) All limits are specified by test or statistical analysis.
(3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and depend on the application and configuration. The typical values are not tested and are not specified on shipped
production material.
(4) This parameter is specified by design and/or characterization and is not tested in production.
