Independent developers often host specialized logic libraries. Searching for "LTspice digital logic" on GitHub often yields collections like the digital library 10000.zip . How to Install Your New Library To expand your toolkit, you can download and
While LTspice is a powerhouse for analog simulation, many users find its native digital gate options a bit limited for complex logic design. To expand your toolkit, you can download and install a to access a wider range of components like multi-input gates, flip-flops, and shift registers.

Once you have downloaded your library (usually a .zip file containing .lib and .asy files), follow these steps to integrate it: 02 Adding Digital Library in LTSpice
While primarily focused on passive components, their library includes integrated circuit models that can be synced via the GitHub repository or Würth Elektronik's website .
