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.
