The CD4000.lib library is an essential third-party resource for engineers simulating classic CMOS digital logic circuits in LTspice. While LTspice provides basic logic gates, it does not include the full range of 4000-series integrated circuits (ICs) like counters, shift registers, and bilateral switches.
