The is a legacy CMOS 8-channel analog multiplexer/demultiplexer. While manufacturers like Texas Instruments do not always provide a standalone official SPICE model for this specific part, you can find community-verified models and alternative methods for simulation. Available SPICE Model Resources

Open the standard library file or create a dedicated CMOS.lib file, and paste the CD4051 subcircuit code at the bottom. cd4051 spice model link

The lack of a manufacturer-backed CD4051 model is an inconvenience, but not an insurmountable one. With the community-built SwitchAna.Lib, the ngspice model, and the ideal switch workaround, you have a full toolset to simulate any circuit using this versatile multiplexer. Your choice depends on your simulator, accuracy requirements, and skill level, but the path forward is clear.

To help you choose the right approach for your project, here is a summary of the available options: that use CD4051 models: The is a legacy

or Yahoo Groups archives (now migrated to groups.io). You’ll find the CD4051 model bundled in the Standard CD4000 Library

: The best source for LTspice users is usually the built-in library, specifically the "SwitchAna" library. It contains modeling for 4000-series CMOS switches. The lack of a manufacturer-backed CD4051 model is

. Ensure your digital control voltages match the supply architecture.

): Check if the signal attenuates slightly when passing through the switch. An ideal model won't show this, but a realistic model will simulate the voltage drop across the internal resistance. Ensure your simulation respects the

(Inhibit) pin logic. Many simplified models skip this, which can lead to "ghost" signals in your simulation where multiple channels appear active at once. format the specific SPICE subcircuit code
