8.0 Electrical Characteristics
8.7 AC Characteristics
The following tables list the AC characteristics including output delays, input setup requirements, input hold requirements
and output float delays. The rising-clock-edge reference level V
Input or output signals must cross these levels during testing.
Input setup and hold times are specified minimums that define the smallest acceptable sampling window for which a syn-
chronous input signal must be stable for correct operation.
Note: All AC tests are at V
T
The interface signal groups listed in Table 11. adhere to the timing parameters given in the corresponding specification.
For details, refer to those specifications.
