Cd4051 Spice Model Link __link__ Now

The CD4051 is essentially an 8-to-1 decoder attached to 8 transmission gates. You can build a functional model by:

The first result was a dead university FTP server from 2009. The second was a forum thread where someone asked the same question, and the only reply was: "Just use an ideal switch array, lol." She sighed. Ideal switches didn't capture the CD4051's notorious on-resistance variation or the crosstalk between channels.

While no single "official" download exists, you can obtain functional models through community libraries and third-party archives: LTspice Community Library: LTspice Groups.io forum hosts a file named SwitchAna.lib cd4051 spice model link

Once you have obtained the CD4051 SPICE model, you can use it in your SPICE simulator to analyze the behavior of the IC in various circuits. Here are the general steps:
