What are the Disadvantages of multiplexer?

Multiplexers can introduce latency, as they require time to switch between input signals, which can be problematic in time-sensitive applications. Additionally, they can be more complex to design and implement compared to simpler circuits, potentially increasing costs and development time. Moreover, as the number of inputs increases, the complexity and size of the multiplexer can become unwieldy, leading to challenges in circuit layout and signal integrity. Lastly, multiplexers may also suffer from signal degradation or crosstalk, particularly in high-frequency applications.
