Switching Waveforms
Read Cycle No. 1
[10, 11]
Read Cycle No. 2
[11, 12]
Write Cycle No. 1 (CE Controlled)
[13]
Notes:
9. No input may exceed V
CC
+ 0.5V.
10.Device is continuously selected, CE
= V
IL
.
11. WE
is HIGH for read cycle.
12.Address valid prior to or coincident with CE
transition LOW.
13.If CE
goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
