DEPTH EXPANSION CONFIGURATION —

usingthreeIDT72205LB/72215LB/72225LB/72235LB/72245LBs. Maximum
depth is limited only by signal loading. Follow these steps:
1. The first device must be designated by grounding the First Load (FL)
control input.
2. All other devices must have FL in the HIGH state.
3. The Write Expansion Out (WXO) pin of each device must be tied to
the Write Expansion In (WXI) pin of the next device. See Figure 21.
4. The Read Expansion Out (RXO) pin of each device must be tied to the
Read Expansion In (RXI) pin of the next device. See Figure 21.
5. All Load (LD) pins are tied together.
6. The Half-Full Flag (HF) is not available in this Depth Expansion
Configuration.
7. EF, FF, PAE, and PAF are created with composite flags by ORing
together every respective flags for monitoring. The composite PAE
and PAF flags are not precise.
