Switching Waveforms
Read Cycle No. 1 (Address Transition Controlled)
Read Cycle No. 2 (OE Controlled)
Write Cycle No. 1 (WE Controlled)
Notes:
12. Device is continuously selected. OE, CE = V
13. WE is HIGH for Read cycle.
14. Address valid prior to or coincident with CE transition LOW.
15. Data I/O is high impedance if OE = V
16. If CE goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state.
17. During this period, the I/Os are in output state and input signals should not be applied.
