Switching Waveforms
Read Cycle No. 2 (OE Controlled)
Write Cycle No. 1 (CE Controlled)
Notes:
15. WE is HIGH for read cycle.
16. Address valid prior to or coincident with CE transition LOW
17. Data I/O is high impedance if OE or BHE and/or BLE= V
18. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
