Notes:
11. Device is continuously selected. OE, CE = V
IL
.
12. WE is HIGH for read cycle.
13. Address valid prior to or coincident with CE transition LOW.
14. Data I/O is high impedance if OE = V
IH
.
15. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
