Switching Waveforms
Read Cycle No. 2 (OE Controlled)
Write Cycle No. 1 (WE Controlled)
Notes:
16. Address valid prior to or coincident with CE transition LOW.
17. Data IO is high impedance if OE = V
18. If CE goes HIGH simultaneously with WE HIGH, the output remains in high-impedance state.
19. During this period, the IOs are in output state and input signals should not be applied.
