Notes:
1. VIH(MAX) = VCC + 2.0V for pulse width less than 6ns.
2. VIL(MIN) = VSS - 2.0V for pulse width less than 6ns.
3. Over/Undershoot specifications are characterized on engineering evaluation stage, not for mass production test.
4. Typical values are included for reference only and are not guaranteed or tested.
Typical valued are measured at VCC = VCC(TYP.) and TA = 25℃

2.Device is continuously selected OE# = low, CE# = low, CE2 = high, LB# or UB# = low.
3.Address must be valid prior to or coincident with CE# = low, CE2 = high, 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 or CE2 must be low during all address transitions.
2.A write occurs during the overlap of a low CE#, high CE2, 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 and CE2 high 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.
