the device where R is used).
Single Device Mode
A single IDT72V81/72V82/72V83/72V84/72V85 may be used when the
applicationrequirementsarefor512/1,024/2,048/4,096/8,192wordsorless.

are for greater than 512/1,024/2,048/4,096/8,192 words. Figure 14 demon-
strates a four-FIFO Depth Expansion using two IDT72V81/72V82/72V83/
72V84/72V85s. Any depth can be attained by adding additional IDT72V81/
72V82/72V83/72V84/72V85s.TheseFIFOsoperateintheDepthExpansion
mode when the following conditions are met:
1. ThefirstFIFOmustbedesignatedbygroundingtheFirstLoad(FL)control
input.
2. All other FIFOs must have FLin the high state.
3. TheExpansionOut(XO)pinofeachdevicemustbetiedtotheExpansion
In (XI) pin of the next device. See Figure 14.
4. ExternallogicisneededtogenerateacompositeFullFlag(FF)andEmpty
Flag (EF). This requires the ORing of all EFs and ORing of all FFs (i.e. all
must be set to generate the correct composite FFor EF). See Figure 14.
