(1) All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless
otherwise specified.
(2) All typicals are given for V_CC = 3.3V and T_A = 25°C.
(3) The algebraic convention, in which the least positive (most negative) limit is designated as minimum, is used in this datasheet.
(4) C_L includes fixture capacitance and C_D includes probe capacitance.
(5) Not production tested. Guaranteed by a statistical analysis on a sample basis at the time of characterization.
