Note 9:
Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The speci-
fication applies to any outputs switching in the same direction, either HIGH to LOW (t
OSHL
) or LOW to HIGH (t
OSLH
). Parameter guaranteed by design.
