1K x 9 DualSync FIFO, 3.3V

The 72V821is a 1K x 9 dual synchronous FIFO that is functionally equivalent to two 72V221 FIFOs in a single package with all associated control, data, and flag lines assigned to separate pins. Each FIFOs has a 9-bit input and output data port. 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.
