: While onsemi provides modern "Physical and Scalable" SPICE models for newer components, older parts like the CD4051 may be found within their legacy application notes or ZIP archives under "Technical Documentation" on the specific product landing page.

: Provides CAD symbols and footprints along with occasional simulation models. You can find the TI CD4051 on SnapMagic to download bundled ECAD and simulation data. cd4051 spice model link

Even with a valid , simulations fail. Here is your troubleshooting cheat sheet: : While onsemi provides modern "Physical and Scalable"

LTspice will generate a standard box symbol. Note that the pins may be arranged randomly, so you may want to manually edit the symbol for a cleaner schematic. Pinout Verification: Even with a valid , simulations fail

The CD4051 is a complex IC that consists of multiple analog switches, which can be configured as a multiplexer or demultiplexer. Its SPICE model must accurately represent the device's behavior, including its electrical characteristics, switching times, and other relevant parameters. A reliable CD4051 SPICE model will help you:
