Texas Instruments' SN74ALS2238FNR is a 64 x 9 bi-directional FIFO memory device from the 74ALS2238 series. This synchronous TTL component offers a maximum access time of 29ns and a cycle time of 25ns, supporting parallel data transfer. Its memory organization provides 64 words with a 9-bit width, totaling 576 bits of storage. The device operates from a 4.5V to 5.5V supply voltage range and features 3-state outputs. The SN74ALS2238FNR is housed in a 44-terminal PQCC (JEDEC S-PQCC-J44) package, suitable for surface mounting. It finds application in telecommunications, industrial automation, and general-purpose digital systems requiring high-speed data buffering and flow control. The bypass transceiver feature further enhances its utility in complex signal routing scenarios.
