signal transition levels
The data in this section is shown for the 3.3-V version. Note that some of the signals use different reference
voltages, see the recommended operating conditions table. Output levels are driven to a minimum logic-high
level of 2.4 V and to a maximum logic-low level of 0.8 V.
Figure 23 shows output levels.

Figure 23. 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 24 shows the input levels.

Figure 24. 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-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.
