2.Device is continuously selected OE# = low, CE# = low, LB# or UB# = low.
3.Address must be valid prior to or coincident with CE# = low, LB# or UB# = low transition; otherwise tAA is the limiting parameter.
4.tCLZ, tBLZ, tOLZ, tCHZ, tBHZ and tOHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state.
5.At any given temperature and voltage condition, tCHZ is less than tCLZ , tBHZ is less than tBLZ, tOHZ is less than tOLZ.

WRITE CYCLE 3 (LB#,UB# Controlled) (1,2,5,6)
Notes :
1.WE#,CE#, LB#, UB# must be high during all address transitions.
2.A write occurs during the overlap of a low CE#, 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 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.
