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.

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.
