Product details

Asynchronous FIFO in a 16-DIP — what you need to know

The 67L401N: Asynchronous FIFO, 64 x 4 memory, 45 ns access time, 10 MHz data rate. 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.

Frequently asked questions

What is the replacement for 67L401N?

No official replacement or successor part number is listed for the 67L401N. 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.

Can 67L401N be replaced by 67L400N?

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.
