Switching Waveforms
Write Cycle No. 1 (WE Controlled)
Notes:
11. Device is continuously selected. OE, CE = V
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
15. If CE goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state.
16. During this period, the I/Os are in output state and input signals should not be applied.
