Frequently asked questions

What is the function of CD74HC40105M?

The CD74HC40105M is an asynchronous FIFO register with a 64-bit (16 x 4) memory array. It buffers data in a first-in-first-out order, supporting depth and width expansion for larger buffering needs.

What is the equivalent of CD74HC40105M?

The evidence does not list a direct pin-compatible equivalent. The closest functional peer is the SN74ACT72241L20RJ, but that part is in a different package (Bulk) and series (74ACT), so verify footprint and logic levels before substituting.
