Cd4051 Spice Model — Link

Once you have obtained a model file (like .lib , .sub , or .cir ), you need to integrate it into your simulation environment. The process varies slightly between different SPICE software.

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.

Because the CD4051 is a legacy component, official manufacturer SPICE files can sometimes be elusive, though active semiconductor manufacturers provide modern equivalents. The most reliable resources are outlined below: Once you have obtained a model file (like
