Read Cycle
Notes:
1. t
OD,
t
ODo
, t
BD
, and t
ODW
are defined as the time at which
the outputs achieve the open circuit condition and are
not referenced to output voltage levels.
2. If CE#, LB#, or UB# goes low at the same time or before
WE# goes high, the outputs will remain at high impedance.
3. If CE#, LB#, or UB# goes low at the same time or after WE#
goes low, the outputs will remain at high impedance.
