specification.
For test conditions, see

, Figures A, B.
These parameters are specified with CL = 5pF, as in Figures B. Transition is measured
±
500mV from steady-state voltage.
This parameter is guaranteed, but not tested.
WE
is High for read cycle.
CE
and
OE
are Low for read cycle.
Address valid prior to or coincident with
CE
transition Low.
All read cycle timings are referenced from the last valid address to the first transitioning address.
All write cycle timings are referenced from the last valid address to the first transitioning address.
