What this synchronous FIFO does in your design
The SN74ACT72231L20RJ is a synchronous unidirectional FIFO memory organized as 2K x 9 bits. It buffers data between two clock domains or bus widths in a single direction — think of it as a first-in-first-out elastic store for a 9-bit parallel bus. Typical applications include rate-matching between a fast DMA controller and a slower peripheral, or temporary storage in a data-acquisition pipeline where bursty writes need to be smoothed out for a steady read clock.
Package and handling note
This part ships in Bulk — loose tubes or trays, not tape-and-reel. If your pick-and-place line expects embossed tape, you will need to transfer to a feeder-compatible carrier or hand-place. Bulk is common for engineering samples and low-volume production runs, but verify your insertion method before committing the line.
