Note 1: “Absolute Maximum Ratings” are those beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device should
be operated at these limits. The tables of “Electrical Characteristics” provide conditions for actual device operation.
Note 2: 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.
Note 3: All typicals are given for VCC = 3.3V and TA = 25°C.
Note 4: The algebraic convention, in which the least positive (most negative) limit is designated as minimum, is used in this datasheet.
Note 5: tSKD1, |tPLHD − tPHLD|, is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of
the same channel.
Note 6: tSKD3, Part-to-Part Skew, is defined as the difference between the minimum and maximum specified differential propagation delays. This specification
applies to devices at the same VCC and within 5°C of each other within the operating temperature range.
Note 7: Stimulus and fixture jitter has been subtracted.
Note 8: CL includes fixture capacitance and CD includes probe capacitance.
Note 9: Not production tested. Guaranteed by a statistical analysis on a sample basis at the time of characterization.
