in
Table 16
)
3.3 AC Electrical Characteristics
Timing waveforms in
Section 3.3
are tested using the V
IL
and V
IH
levels specified in the DC
Characteristics table.
In
Figure 4
the levels of V
IH
and V
IL
for an input signal are shown.
Figure 4. Input Signal Measurement References
Figure 5
shows the definitions of the following signal states:
Active state, when a bus or signal is driven, and enters a low impedance state.
Tri-stated, when a bus or signal is placed in a high impedance state.
Data Valid state, when a signal level has reached V
OL
or V
OH.
Data Invalid state, when a signal level is in transition between V
OL
and V
OH.
