Notes
18. Data I/O is high impedance if OE
or BHE and/or BLE = V
IH
.
19. If CE
1
goes HIGH simultaneously with WE going HIGH, the output remains in a high impedance state.
20. CE
is the logical combination of CE
1
and CE
2
. When CE
1
is LOW and CE
2
is HIGH, CE is LOW; when CE
1
is HIGH or CE
2
is LOW, CE is HIGH.

goes HIGH simultaneously with WE going HIGH, the output remains in a high impedance state.
23. CE
is a shorthand combination of both CE
1
and CE
