signal transition levels
The data in this section is shown for both the 5-V version (’C5x) and the 3.3-V version (’LC5x). In each case,
the 5-V data is shown followed by the 3.3-V data in parentheses. TTL-output levels are driven to a minimum
logic-high level of 2.4 V (2 V) and to a maximum logic-low level of 0.6 V (0.4 V). Figure 10 shows the TTL-level
outputs.

1 V (0.8 V)
2 V (1.6 V)
2.4 V (2 V)
Figure 10. TTL-Level Outputs
TTL-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 2 V (1.6 V), and the
level at which the output is said to be low is 1 V (0.8 V).
For a low-to-high transition the level at which the output is said to be no longer low is 1 V (0.8 V), and the
level at which the output is said to be high is 2 V (1.6 V).
Figure 11 shows the TTL-level inputs.
2 V (1.8 V)
0.8 V (0.6 V)
Figure 11. TTL-Level Inputs
TTL-compatible input transition times are specified as follows:
For a high-to-low transitionon an input signal, the level at which the input is said to be no longer high is
2 V (1.8 V), and the level at which the input is said to be low is 0.8 V (0.6 V).
For a low-to-high transition on an input signal, the level at which the input is said to be no longer low is
0.8 V (0.6 V), and the level at which the input is said to be high is 2 V (1.8 V).
