4
Note 6: An initial pause of 500 μs is required after power-up followed by a minimum of eight initialization cycles (RAS-only refresh or CAS before RAS refresh
cycles).
Note the RAS may be cycled during the initial pause. And 8 initialization cycles are required after prolonged periods (greater than 8.2ms) of RAS
inactivity before proper device operation is achieved.
7: Measured with a load circuit equivalent to 2TTL loads and 100pF.
8: Assumes that

. If
t
RCD
or
t
RAD
is greater than the maximum recommended value shown in this table,
t
RAC
will increase by amount that
t
RCD
exceeds the value shown.
10: Assumes that

ASC
≥

.
12:
t
OFF(max)

OEZ (max)
defines the time at which the output achieves the high impedance state (I
OUT
≤
±10 μA ) and is not reference to V
