Hi everyone,
: Input and output capacitances (typically ~30 pF) affect high-frequency signal integrity and settling times. How to Implement the CD4051 in LTspice

If you have a working model, please share. If not, any tips on modeling charge injection or Ron(R,V) in LTspice would be great.
resistance, propagation delays, and break-before-make behavior. Overview of the CD4051 IC
The digital section consists of the level shifting and decoding circuitry. In a physical CD4051, this logic allows the device to select one of eight channels based on three binary control inputs (A, B, C) and an inhibit pin. In a SPICE model, this is often implemented using primitive logic gates (AND, NOT, OR) or behavioral sources. The fidelity of this block is crucial; the model must replicate the propagation delay ($t_pd$) and transition times to accurately simulate timing hazards or race conditions in high-speed switching applications.
