Operation modes
Note:
met, valid data will be available after the latter of the chip enable access time (tELQV) or
output enable access time (tGLQV).
The state of the eight three-state data I/O signals is controlled by E and G. If the outputs are
activated before tAVQV, the data lines will be driven to an indeterminate state until tAVQV.
If the address inputs are changed while E and G remain active, output data will remain valid
for output data hold time (tAXQX) but will be indeterminate until the next address access.
