Figure 6-5. Output Levels

Output transition times are specified as follows:

•For a high-to-low transition, the level at which the output is said to be no longer high is below 80% of the total voltage range and lower and the level at which the output is said to be low is 20% of the total voltage range and lower.

•For a low-to-high transition, the level at which the output is said to be no longer low is 20% of the total voltage range and higher and the level at which the output is said to be high is 80% of the total voltage range and higher.

Figure 6-6shows the input levels.

Figure 6-6. Input Levels

Input transition times are specified as follows:

•For a high-to-low transition on an input signal, the level at which the input is said to be no longer high is 90% of the total voltage range and lower and the level at which the input is said to be low is 10% of the total voltage range and lower.

•For a low-to-hightransition on an input signal, the level at which the input is said to be no longer low is 10% of the total voltage range and higher and the level at which the input is said to be high is 90% of the total voltage range and higher.
