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 9. DC and AC Measurement Conditions

Note: Output High Z is defined as the point where data is no longer driven (see Table 9., page 18).
