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).
