4. For C
L
= 50pF, add approximately 300ps to the AC maximum specification.
5. 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 specification 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.

6. Number of outputs defined as “n”. Measured with “n–1” outputs switching from HIGH–to–LOW or LOW–to–HIGH. The remaining output is
measured in the LOW state.
7. Number of outputs defined as “n”. Measured with “n–1” outputs switching from HIGH–to–LOW or LOW–to–HIGH. The remaining output is
measured in the HIGH state.
