Cd4051 Spice Model - Link

can operate up to 20V, simulation models may require specific MOSFET parameters (W and L) to accurately reflect the 100+ Ωcap omega ON resistance found at lower voltages like 5V.

The CD4051 is a classic CMOS 8-channel analog multiplexer/demultiplexer. Finding an official SPICE model can be tricky because major manufacturers like Texas Instruments can operate up to 20V, simulation models may

After years of forum crawling and vendor link hunting, the most robust remains the official Texas Instruments model for the CD4051B. Use this direct approach: can operate up to 20V
