NOTES:

1. R/W or CE or UB and LB must be HIGH during all address transitions.

4. During this period, the I/O pins are in the output state and input signals must not be applied.

5. If the CE or SEM LOW transition occurs simultaneously with or after the R/W LOW transition, the outputs remain in the High-impedance state.

6. Timing depends on which enable signal is asserted last, CE or R/W.

7. This parameter is guaranteed by device characterization, but is not production tested. Transition is measured 0mV from steady state with the Output Test Load
