AC CHARACTERISTICS—WRITE CYCLE
(V
CC = 5V ± 10%, All Temperature Ranges)
(2)
TIMING WAVEFORM OF WRITE CYCLE NO. 1 (WE
WE
WE
WE
WE CONTROLLED)(10,11)
Notes:
10. CE and WE must be LOW for WRITE cycle.
11. OE is LOW for this WRITE cycle to show t
WZ and tOW.
12. If CE goes HIGH simultaneously with WE HIGH, the output remains
in a high impedance state
13. Write Cycle Time is measured from the last valid address to the first
transitioning address.
