SN74ACT7200L15DV 256 x 9 Async FIFO, 15 ns Access

The Texas Instruments SN74ACT7200L15DV is a 256-word by 9-bit asynchronous FIFO memory. The '15' in the order code signals a 15 ns access time, which governs how fast the read pointer can present data on the output bus after the read-enable edge. For an asynchronous FIFO, that access time sets the maximum sustainable read rate and the timing margin against the downstream logic's setup window. If the rest of the bus runs at 50 MHz or slower, this part clears the hold and setup budget without extra wait states. The 9-bit width (8 data bits plus a parity/flag bit) suits byte-wide data paths with an error-detection overlay.
