Switching Waveforms
Read Cycle No. 1
Read Cycle No. 2
Write Cycle No. 1 (WE Controlled)
Notes:
10. WE is HIGH for read cycle.
11. Device is continuously selected. OE, CE = V
12. Address valid prior to or coincident with CE transition LOW.
13. Data I/O pins enter high-impedance state, as shown, when OE is held LOW during write.
