You can download a reliable CD4051 SPICE model from the Texas Instruments website: https://www.ti.com/lit/zip/sbah001 . This model has been verified and validated by the manufacturer, ensuring its accuracy and compatibility with popular SPICE simulators.
These characteristics make it ideal for a vast range of applications, including signal routing, data acquisition systems, audio switching, and analog-to-digital converter input channel selection. Given its importance, the ability to simulate it accurately is critical.

: Sites like DatasheetArchive aggregate various older models, though these should be tested against the physical CD4051 datasheet to ensure the RONcap R sub cap O cap N end-sub (On-Resistance) matches your specific voltage range. How to Use a CD4051 Subcircuit in LTspice
Method 2: Adding to the Global LTspice Library (Best for long-term use) Copy the text inside your downloaded CD4051 model file. You can download a reliable CD4051 SPICE model
If you are using PSpice, Multisim, or another simulator, the general principle is the same:
To use the CD4051 SPICE model in your circuit simulations, follow these steps: Given its importance, the ability to simulate it
Other manufacturers, like NXP (which offers the ), also do not prominently provide a native SPICE model, though their device is a functional equivalent. This means that the responsibility of creating or finding a working model often falls upon the user community.
: The SwitchAna.Lib file has been integrated into the EasyEDA online simulation platform. The project "CMOS 4016 and 4066 analogue switches" explicitly states that its SPICE models are based on the SwitchAna.Lib developed by user Robertugo_2005. This is a good validation of the model's acceptance and use within the broader community.
