FIFO organization and bus fit
The SN74ACT72241L20RJR is a synchronous unidirectional FIFO organized 4K deep by 9 bits wide. The 9-bit word width maps to a byte-wide data path with a parity bit — common in telecom backplanes and DSP interconnects where a ninth bit carries sideband or error-detection data. Depth of 4096 words provides enough buffering to absorb burst traffic between a fast processor and a slower peripheral without dropping frames, as long as the average fill rate stays below the drain rate.
