AC CHARACTERISTICS (t R = t F = 2.5ns; C L = 50pF; R L = 500 )
3. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.
4. Number of outputs defined as “n”. Measured with “n–1” outputs switching from HIGH–to–LOW or LOW–to–HIGH. The remaining output is
