Spice Model Link: Cd4051
CD4051
To find and use a (8-Channel Analog Multiplexer/Demultiplexer) SPICE model, you typically need to source it from third-party libraries or manufacturer archives, as modern manufacturers like Texas Instruments do not provide official models for these legacy parts. 1. Where to Find CD4051 SPICE Models
Add Include Directive
: Use the Spice Directive tool (press S ) to add .include your_model_filename.lib to your schematic. cd4051 spice model link
Because the CD4051 is essentially a set of eight voltage-controlled switches and a 3-to-8 decoder, many SPICE veterans don't use a link at all. They use a generic CD4051 To find and use a (8-Channel Analog
The CD4051 SPICE model is a specific model that represents the behavior of the CD4051 analog multiplexer/demultiplexer IC. This model can be used to simulate the performance of the CD4051 in various applications, including: Texas Instruments: https://www

⚡ Quick Tip for LTSpice Users
- Navigate to the "Design & Development" tab.
- Select "Design tools & simulation."
- Look for "SPICE Model" (usually a
.libor.modfile) or "TINA-TI Reference Design."
transistor-level model
For high-precision applications (e.g., audio switching), look for a (rare for CD4051). If you cannot find one, add external parasitic capacitors to your simulation to model crosstalk.
