Notes
Document Number: 38-05475 Rev. *F
13. Device is continuously selected. OE, CE = V
14. WE is HIGH for read cycle.
15. Address valid prior to or coincident with CE transition LOW.
16. Data IO is high impedance if OE = V
17. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high impedance state.
