Texas Instruments SNJ54ALS235FK is a 64-word by 5-bit asynchronous FIFO buffer from the 54ALS235 series. This component offers a maximum access time of 24 ns and a typical cycle time of 50 ns, supporting a maximum clock frequency of 20 MHz. The memory organization is 64 words deep with a 5-bit data width, resulting in a total memory density of 320 bits. It operates with TTL technology and features 3-state outputs with an output enable function. The device is housed in a 20-terminal Ceramic Quad Flatpack (CQFP) package with a square shape and a terminal pitch of 1.27 mm. This component is suitable for applications requiring high-speed data buffering in demanding environments, including aerospace and defense. The operating temperature range is from -55°C to +125°C, with a nominal supply voltage of 5V (4.5V to 5.5V).
