... XIS Figure 11. Expansion In 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. These FIFOs operate in the Depth Expansion mode when the following conditions are met: 1. The first FIFO must be designated by grounding the First Load (FL) control input ...

... Bidirectional Operation Applications which require data buffering between two systems (each system capable of Read and Write operations) can be achieved by pairing IDT72V81/72V82/72V83/72V84/72V85s as shown in Figure 16. Both Depth Expansion and Width Expansion may be used in this mode. Data Flow-Through Two types of flow-through modes are permitted, a read flow-through and write flow-through mode ...
