Note 9:
The specified limits represent the
“
worst case
”
value for the parameter. Since these values normally occur at the temperature extremes, additional
noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are cho-
sen to guarantee operation under
“
worst case
”
conditions.

Note 11:
t
PS
describes opposite edge skews, i.e. the difference between the delay of a differential output signal pair's LOW-to-HIGH and HIGH-to-LOW prop-
agation delays. With differential signal pairs, a LOW-to-HIGH or HIGH-to-LOW transition is defined as the transition of the true output or input pin.
Note 12:
t
OSLH
describes in-phase gate differential propagation skews with all differential outputs going LOW-to-HIGH; t
OSHL
describes the same conditions
except with the outputs going HIGH-to-LOW.
Note 13:
t
OST
describes the maximum worst case difference in any of the t
PS
, t
OSLH
or t
OST
delay paths combined.
Note 14:
The skew specifications pertain to differential I/O paths.
