Notes : 1. WE or CE 1 must be HIGH or CE2 must be LOW during all address transitions. 2. A write occurs during the overlap of a low CE 1 , a high CE2 and a low WE . 3. During a WE controlled with write cycle with OE LOW, tWP must be greater than tWHZ+tDW to allow the I/O 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 singals must not be applied. 4. If the CE 1 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.
