5. The tSKEWr specification guarantees that the rising edges
of outputs Q/2, Q0, Q1, Q2, Q3, and Q4 will always fall
within a 500ps window within one part. However, if the
relative position of each output within this window is not
specified, the 500 ps window must be added to each side
of the tPD specification limits to calculate the total
part–to–part skew. For this reason the absolute
distribution of these outputs are provided in table 2. When
taking the skew data, Q0 was used as a reference, so all
measurements are relative to this output. The information
in Table 2 is derived from measurements taken from the
14 process lots described in Note 1, over the temperature
and voltage range.
