NOTES: A. tsk(o), CLK to Q, is calculated as the greater of:
– The difference between the fastest and slowest of tPLHn ( n = 1, 2, 3, 4, 5, 6)
– The difference between the fastest and slowest of tPHLn ( n = 1, 2, 3, 4, 5, 6)
B. tsk(o), CLK to Q, is calculated as the greater of: | tPLH7 – tPLH8 | and | tPHL7 – tPHL8 |.
C. tsk(o), CLK to Q and Q, is calculated as the greater of:
– The difference between the fastest and slowest of tPLHn ( n = 1, 2, 3, 4, 5, 6), tPHL7, and tPHL8
– The difference between the fastest and slowest of tPHLn ( n = 1, 2, 3, 4, 5, 6), tPLH7, and tPLH8
D. tsk(p) is calculated as the greater of | tPLHn – tPHLn | ( n = 1, 2, 3, . . ., 8 ).
