*1: The output load is 30 pF.
*2: The output load is 5 pF.
*3: The tCE is applicable if OE is brought to Low before CE1s goes Low and is also applicable if actual value of both
or either tASO or tCLOL is shorter than specified value.
*4: Applicable only to A0 and A1 when both CE1s and OE are kept at Low for the address access.
*5: Applicable if OE is brought to Low before CE1s goes Low.
*6: The tASO, tCLOL (Min) and tOP (Min) are reference values when the access time is determined by tOE.
If actual value of each parameter is shorter than specified minimum value, tOE becomes longer by the amount
of subtracting actual value from specified minimum value.
For example, if actual tASO, tASO (actual) , is shorter than specified minimum value, tASO (Min) , during OE control
access (i.e., CE1s stays Low) , the tOE becomes tOE (Max) + tASO (Min) − tASO (actual) .
*7: The tASO[ABS] and tOP[ABS] are the absolute minimum values during OE control access.
*8: If actual value of either tCLOL or tOP is shorter than specified minimum value, both tOLAH and tOLCH become tRC (Min)
− tCLOL (actual) or tRC (Min) − tOP (actual) .
*9: Maximum value is applicable if CE1s is kept at Low.
