DYNAMIC SWITCHING CHARACTERISTICS

1) 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.

AC ELECTRICAL CHARACTERISTICS

1) Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the same device switch-

2) Parameter guaranteed by design
