3.Address must be valid prior to or coincident withCE =low, LB orUB =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 lowCE , low WE ,LB orUB =low.
3.During a WE controlled write cycle withOE 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 theCE ,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.
