Notes:

16. Data I/O is high impedance if OE = VIH .

17. If Chip Enable goes INACTIVE and CE2 goes LOW simultaneously with WE = V IH, the output remains in a high-impedance state.

18. During the DON’T CARE period in the DATA I/O waveform, the I/Os are in output state and input signals should not be applied.
