Notes :
1. WE is high for read cycle.
2.Device is continuously selected OE =low, CE =low.
3.Address must be valid prior to or coincident with CE =low,; otherwise tAA is the limiting parameter.
4.tCLZ, tOLZ, tCHZ 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, tOHZ is less than tOLZ.

Notes :
1. WE , CE must be high during all address transitions.
2.A write occurs during the overlap of a low CE , low WE .
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 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.
