DC AND AC PARAMETERS
This section summarizes the operating and mea-
surement conditions, as well as the DC and AC
characteristics of the device. The parameters in
the following DC and AC Characteristic tables are
derived from tests performed under the Measure-
ment Conditions listed in the relevant tables. De-
signers should check that the operatingconditions
in their projects match the measurement condi-
tions when using the quoted parameters.
Table 3. DC and AC Measurement Conditions
Note: Output Hi-Z is defined as the point where data is no longer driven.
Figure 8. AC Testing Input/Output Waveforms
Note: 50pF for M41ST84W.
