TI is the gold standard for simulation models regarding the CD4000 series. Many engineers host SPICE models on GitHub for public use
: You can download the widely used CD4000_v.lib which includes subcircuits for various 4000-series logic, including multiplexers. GitHub Repositories : You can download the widely used CD4000_v
While Analog Devices does not manufacture the CD4051, the community and ADI utility libraries often include generic CMOS multiplexers or specific CD4051 models.
If you cannot find a link and need to approximate the behavior using a subcircuit of ideal switches and logic gates, use these typical Texas Instruments CD4051B datasheet ON Resistance ( cap R sub o n end-sub : Typically : Approximately Supply Voltage Switching Type : Break-before-make. Where to Check for Updates Texas Instruments : While they currently only provide symbols and footprints on SnapEDA, check the "Design & development" tab on the CD4051B product page for any newly released PSpice models. : Check their simulation and modeling support for newer 74HC/HCT4051 variants. file into a specific simulator like
