NOTES: A. Output skew, tsk(o), from CLK↑ to Y↑, is calculated as the greater of the difference between the fastest and slowest of

tPLHn (n = 1, 2, 3, 4) or tPLHn (n = 9, 10, 11, 12).

B. Output skew, tsk(o), from CLK↑ to Q↑, is calculated as the greater of the difference between the fastest and slowest of

tPLHn (n = 5, 6, 7, 8).

C. Output skew, tsk(o), from CLK↑ to Y↑ and Q↑, is calculated as the greater of the difference between the fastest and slowest of

tPLHn (n = 1, 2, ..., 8).
