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