Notes
5. tWZ and tHZ is specified with a load capacitance of 5 pF. Transition is measured when the outputs enter a high impedance state.
6. This parameter is characterized but not 100% tested.
7. The relationship between CE and WE determines if a CE or WE controlled write occurs. There is no timing specification associated with this relationship.
