The Texas Instruments SN74ALS235DW is a 64x5 asynchronous FIFO memory device. This TTL-compatible component offers a maximum access time of 22ns and a maximum clock frequency of 25MHz, with a cycle time of 40ns. Its memory organization is 64 words by 5 bits, providing a total memory density of 320 bits. Designed for surface mounting, it is housed in a 20-pin PDSO (Plastic Dual Small Outline) package with a gull-wing terminal form and a 1.27mm terminal pitch. The device features 3-state outputs with an output enable function and operates with a nominal supply voltage of 5V, ranging from 4.5V to 5.5V. Typical applications include data buffering and synchronization in telecommunications, industrial control, and computing systems. The operating temperature range is 0°C to 70°C.
