Notes:
4. AC characteristics (except High-Z) for 10-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).
5. 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.
6. t
POWER
gives the minimum amount of time that the power supply should be at typical V
values until the first memory access can be performed.
7. t
, t
, and t
are specified with a load capacitance of 5 pF as in part (d) of AC Test Loads. Transition is measured
±
500 mV from steady-state voltage
8. At any given temperature and voltage condition, t
is less than t
, t
is less than t
, and t
is less than t
for any given device.
9. 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
either 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.
