Notes : 1.WE#,CE#, LB#, UB# must be high or CE2 must be low during all address transitions. 2.A write occurs during the overlap of a low CE#, high CE2, low WE#, LB# or UB# = low. 3.During a WE# controlled write cycle with OE# low, tWP must be greater than tWHZ + tDW to allow the drivers to turn off and data to be placed on the bus. 4.During this period, I/O pins are in the output state, and input signals must not be applied. 5.If the CE#, LB#, UB# low transition and CE2 high transition occurs simultaneously with or after WE# low transition, the outputs remain in a high impedance state. 6.tOW and tWHZ are specified with CL = 5pF. Transition is measured 500mV from steady state.
