8-ns devices:
AC characteristics (except High-Z) for all 8-ns parts are tested using the load conditions shown in Figure (a). All other speeds are tested using the Thevenin
load shown in Figure (b). High-Z characteristics are tested for all speeds using the test load shown in Figure (d).
Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V.
t
At any given temperature and voltage condition, t
This parameter is guaranteed by design and is not tested.
The internal write time of the memory is defined by the overlap of CE LOW and WE LOW. CE and WE must be LOW to initiate a write, and the transition of any of these
signals can terminate the write. The input data set-up and hold timing should be referenced to the leading edge of the signal that terminates the write.
