Notes:

5.WE is HIGH for READ cycle.

6.CS and OE are LOW for READ cycle.

7.ADDRESS must be valid prior to, or concident with, CS transition

LOW, t

AA must still be met.

TIMING WAVEFORM OF READ CYCLE NO. 1(5,6)

8. Transition is measured ±200 mV from steady state voltage

prior to change, with loading as specified in Figure 1.

9. Read Cycle Time is measured from the last valid address to

the first transitioning address.
