Figure 24. Output Levels
Output transition times are specified as follows:
D 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.
D For alow-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 25 shows the input levels.

Figure 25. Input Levels
Input transition times are specified as follows:
D 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.
D For a low-to-high transition 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.
