6.9 Signal Transition Levels
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
0.4 V.
Figure 6-7 shows output levels.
Figure 6-7. 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 V
OH(MIN)
and the level at which the output is said to be low is V
OL(MAX)
and lower.
• For a low-to-high transition, the level at which the output is said to be no longer low is above V
OL(MAX)
and the level at which the output is said to be high is V
OH(MIN)
and higher.
Figure 6-8 shows the input levels.
Figure 6-8. 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 below V
IH(MIN)
and the level at which the input is said to be low is V
IL(MAX)
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
above V
IL(MAX)
and the level at which the input is said to be high is V
IH(MIN)
and higher.
NOTE
See the individual timing diagrams for levels used for testing timing parameters.
