SOIC and PLCC AC Electrical Characteristics

Note 5: The propagation delay specified is for the switching of a single output. Delays may vary up to 0.40 ns if multiple outputs are switching simultaneously.

Note 6: Output-to-Output Skew is defined as the absolute value of the difference between the actual propagation delay for any outputs within the same pack-
