READ
Figure 5 shows Read cycle waveforms. A read cycle begins
with selection address, chip select and output enable. Chip
select is accomplished by placing the CS# line low. Output
enable is done by placing the OE# line low. The memory
WE512K8, WE256K8,
WE128K8-XCX
places the selected data byte on I/O0 through I/O7 after the
access time. The output of the memory is placed in a high
impedance state shortly after either the OE# line or CS# line
is returned to a high level.
