72205 - Block Diagram
Description
The 72205 is a 256 x 8 First-In, First-Out memory with clocked read and write controls and would be useful for a wide variety of data buffering needs, such as optical disk controllers, Local Area Networks (LANs), and interprocessor communication. These FIFOs have 18-bit input and output ports. The read clock can be tied to the write clock for single clock operation or the two clocks can run asynchronous of one another for dual-clock operation. These devices are depth expandable using a Daisy-Chain technique.
