Note Skew (comp.) in Table 1 is the same as “Skew” in the
datasheet. Also Skew (channel) and Skew (device) are cal-
culations, but are guaranteed by the propagation delay tests.
Both Skew (channel) and Skew (device) would normally be
tighter whenever specified from characterization data.
The information in this section of the datasheet is to help clar-
ity how skew is defined in this datasheet. This should help
when designing the DS89C387 into most applications.
