NOTES: A. tsk(o) CLK to Q are calculated as the greater of:
– The difference between the fastest and slowest of tPLHn (n = 1, 2, 3, 4)
– The difference between the fastest and slowest of tPHLn (n = 1, 2, 3, 4)
B. tsk(o) CLK to Q are calculated as the greater of:
– The difference between the fastest and slowest of tPLHn (n = 5, 6, 7, 8)
– The difference between the fastest and slowest of tPHLn (n = 5, 6, 7, 8)
C. tsk(o) CLK to Q and Q are calculated as the greater of:
– The difference between the fastest and slowest of tPLHn (n = 1, 2, 3, 4), tPHLn (n = 5, 6, 7, 8)
– The difference between the fastest and slowest of tPHLn (n = 1, 2, 3, 4), tPLHn (n = 5, 6, 7, 8)
D. tsk(p) is calculated as the greater of | tPLHn – tPHLn | (n = 1, 2, 3, . . . , 8).
