The SN74ACT7201LA25RJR is a 512 x 9 asynchronous FIFO memory from Texas Instruments, organized as 512 words of 9 bits each. The 9-bit width accommodates an eighth data bit plus a parity or control bit per word, common in bus-oriented data buffering. This part is listed under the Analog & Data Acquisition category, reflecting its role in data-path buffering between acquisition front-ends and processing logic.
Peer comparison for fit
The SN74ACT7202LA15DV and SN74ACT7206L20NP are functional peers within the same 74ACT720x family. The key difference is depth and speed: the SN74ACT7202LA15DV is a 512 x 9 FIFO with a 15 ns access time, while the SN74ACT7206L20NP offers a 20 ns access time. The SN74ACT7201LA25RJR sits at 25 ns — the slowest of the three, but still within the timing budget for many asynchronous bus interfaces.
