Analog Multiplexer design in LTspice

Thread Summary

The user is troubleshooting an ADG408 analog multiplexer in LTspice, specifically how to configure the selection lines (A0, A1, A2) to switch between input signals (S1 to S8). The final answer clarifies that with A0-0, A1-0, and A2-1, the output should be S5, not S2, based on the ADG408 Truth Table. The user is advised to share a screenshot of their simulation results for further assistance.
