DC AND AC PARAMETERS
This section summarizes the operating and mea-
surement conditions, and the DC and AC charac-
teristics of the device. The parameters in the DC
and AC Characteristic tables that follow are de-
rived from tests performed under the Measure-
ment Conditions summarized in the relevant
tables. Designers should check that the operating
conditions in their circuit match the measurement
conditions when relying on the quoted parame-
ters.
Table 39. Operating Conditions (5V devices)
Table 40. Operating Conditions (3V devices)
Table 41. AC Measurement Conditions
Note: 1. Output Hi-Z is defined as the point where data out is no longer driven.
