* NOTE : ICC1, ICC3, ICC4 and ICC6 are dependent on output loading and cycle rates. Specified values are obtained with the output open.
ICC is specified as an average current. In ICC1 and ICC3, address can be changed maximum once while RAS=VIL. In ICC4,
address can be changed maximum once within one EDO mode cycle time, tHPC.

NOTES
An initial pause of 200us is required after power-up followed
1.
by any 8 RAS-only or CAS-before-RAS refresh cycles before
proper device operation is achieved.
2.
Input voltage levels are Vih/Vil. VIH(min) and VIL(max) are reference levels for measuring timing of input signals. Transition
times are measured between VIH(min) and VIL(max) and are
assumed to be 5ns for all inputs.
3.
Measured with a load equivalent to 2 TTL loads and 100pF.
Either tRCH or tRRH must be satisfied for a read cycle.
9.
These parameters are referenced to the CAS leading edge in
early write cycles.
Operation within the tRAD(max) limit insures that tRAC(max)
10.
can be met. tRAD(max) is specified as reference point only. If
UnitNote
tRAD is greater than the specified tRAD(max) limit access time
is controlled by tAA.
4.
Operation within the tRCD(max) limit insures that tRAC(max)
can be met. tRCD(max) is specified as a reference point only.
If tRCD is greater than the specified tRCD(max) limit, then
access time is controlled exclusively by tCAC.
5.
Assumes that tRCD≥tRCD(max).
6.
This parameter defines the time at which the output achieves
the open circuit and is not referenced for VOH or VOL
tWCS is non-restrictive operating parameter. It is included in
7.
the data sheet as electrical characteristics only. If
tWCS≥tWCS(min), the cycle is an early write cycle and the
data out pin will remain high impedance for the duration of
the cycle.
tASC≥6ns, Assume tT=2.0ns.
11.
12.
If RAS goes high before CAS high going, the open circuit
condition of the output is achieved by CAS high going. If CAS
goes high before RAS high going , the open circuit condition
of the output is achieved by RAS going.
