Unidirectional, width-expandable. Operates from 4.75 V to 5.25 V, 0°C to 70°C. 16-DIP through-hole package. ## 64 x 4 memory — what the depth and width mean 64-word by 4-bit FIFO stores 64 bytes. Width expansion supported. No programmable flags or FWFT. ## Package and mounting — legacy DIP footprint The 67L401N is supplied in a 16-pin DIP package (16-PDIP) with through-hole mounting. This is a legacy footprint, still widely used in prototyping, breadboarding, and through-hole production for low-volume or repair applications. The Bulk packaging means it ships in tubes or trays, not on tape-and-reel, so it is not optimized for automated pick-and-place in high-volume SMT lines. For a new design, a surface-mount equivalent (if available in the family) would be preferable for production efficiency, but for a BOM line that requires a through-hole FIFO, this is the direct fit.","metaTitle":"67L401N FIFO 64x4 Async 45ns 10MHz 16-DIP Through Hole","metaDescription":"67L401N asynchronous FIFO, 64 x 4 memory, 45 ns access time, 10 MHz data rate, 4.75-5.25 V supply, 0-70°C, 16-DIP.

The part is still active, so no direct replacement is required. If a RoHS-compliant or surface-mount variant is needed, check the manufacturer's FIFO family for a pin-compatible alternative with similar 64 x 4 depth and 45 ns access time."},{"question":"Can 67L401N be replaced by 67L400N?","answer":"The evidence does not provide a direct cross-reference between the 67L401N and 67L400N. Without a manufacturer-issued equivalence statement, it is not safe to assume pin-compatibility or functional interchangeability. Verify the 67L400N datasheet against the 67L401N's 64 x 4 depth, 45 ns access time, 16-DIP package, and 5 V supply before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/amd-xilinx/67L401N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/amd-xilinx/67L401N when reusing this data.
