Notes :
1. WE is HIGH for a read cycle.
2. Device is continuously selected OE , CE 1 =VIL and CE2=VIH.
3. Address must be valid prior to or coincident with CE 1 low and CE2 high transition; otherwise tAA is the limiting parameter.
4. OE is low.
5. tCLZ1, tCLZ2, tOLZ, tCHZ1, tCHZ2 and tOHZ are specified with CL=5pF. Transition is measured ± 500mV from steady state.
6. At any given temperature and voltage condition, tCHZ1 is less than tCLZ1, tCHZ2 is less than tCLZ2, tOHZ is less than tOLZ.
