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 operating conditions
in their projects match the measurement condi-
tions when using the quoted parameters.
Table 8. DC and AC Measurement Conditions
Note: Output High Z is defined as the point where data is no longer driven (see Table 11, page 25).
Figure 19. AC Testing Load Circuit
Note: 1. CL = 100pF for the M41ST85Y, 50pF for the M41ST85W
