(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 for VCC = +3.3V and TA = +25°C, and at the Recommended Operation Conditions
at the time of product characterization and are not ensured.
(3) Specification is ensured by characterization and is not tested in production.
(4) tSKD1, |tPLHD − tPHLD|, Pulse Skew, is the magnitude difference in differential propagation delay time between the positive going edge and
the negative going edge of the same channel.
(5) tSKD2, Channel to Channel Skew, is the difference in propagation delay (tPLHD or tPHLD) among all output channels in Broadcast mode
(any one input to all outputs).
(6) tSKD3, Part to Part Skew, is defined as the difference between the minimum and maximum differential propagation delays. This
specification applies to devices at the same VCC and within 5°C of each other within the operating temperature range.
