The 72221SyncFIFO™ is a 1K x 9 First-In, First-Out memory with clocked read and write controls. This FIFO is useful for a wide variety of data buffering needs such as graphics, local area networks and interprocessor communication. These FIFOs have 9-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.
