Document #: 38-05442 Rev. *H
25. Data I/O is high impedance if OE = V
26. If CE goes HIGH simultaneously with WE HIGH, the output remains in high impedance state.
27. During this period, the I/Os are in output state and input signals must not be applied.
28. Chip enable (CE) must be HIGH at CMOS level to meet the I
