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-
Table 56. Operating Conditions
Table 57. AC Symbols for PLD Timing
Example: t
Table 58. AC Measurement Conditions
Note: 1. Output Hi-Z is defined as the point where data out is no longer driven.
