Texas Instruments SN74ALS234FN is a 64 x 4-bit asynchronous FIFO memory device. This TTL-compatible component features a maximum access time of 22ns and a maximum clock frequency of 30MHz, with a cycle time of 33.33ns. The memory organization provides 64 words with a data width of 4 bits per word. Output characteristics include 3-state capability with an active-high output enable. The device operates from a nominal supply voltage of 5V, with a range of 4.5V to 5.5V, and a maximum supply current of 148mA. Packaged in a 20-terminal J-leaded chip carrier (PQCC20), its dimensions are 8.9662mm square. This component is suitable for applications in telecommunications, industrial control, and data acquisition systems where high-speed buffering is required.
