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-
Table 5. Operating and AC Measurement Conditions
Note: Output Hi-Z is defined as the point where data is no longer driven.
