Interface - Analog Switches, Multiplexers, Demultiplexers are an important class of components in integrated circuits (ics) that are used to select and switch between different signal paths. Multiplexers are analog switches that combine multiple input signals onto a shared output line. The multiplexer consists of a set of selection lines and a plurality of input lines, and determines which input signal is connected to the output line by selecting the control signal on the line. This design allows multiple signals to be transmitted with limited physical connections, saving wiring resources and space. A demultiplexer is a reverse operation of a multiplexer that distributes one input signal to multiple output lines. By controlling the signal, the demultiplexer can selectively connect the input signal to one or more output lines to achieve signal distribution and routing. Such IC chips achieve lossless switching of signals through integrated transistors or MOSFET devices, and the design principle is to use control signals to change the conductivity of semiconductor materials, so as to switch between signal paths. The analog switch can be bi-directional, allowing the signal to travel in both directions, or unidirectional, allowing the signal to flow in only one direction.
Application
Interface - Analog Switches, Multiplexers, Demultiplexers have demonstrated extensive application value in multiple fields. In data acquisition systems, they are used for switching multiple signals, reducing the number of connections between sensors and processors, and improving the flexibility and efficiency of the system. In the field of communication, especially in multi-channel transmission systems, multiplexers are used to merge multiple signals into one medium for transmission, while demulsifiers separate signals at the receiving end, achieving effective signal management and transmission. In testing and measurement equipment, this type of IC chip is used for dynamic control of signal paths, supporting multiple testing modes and configurations. In addition, analog switches, multiplexers, and demulsifiers play a crucial role in audio processing, video switching, automotive electronics, medical equipment, and various industrial control systems that require signal switching and management, providing a solid foundation for the high performance and versatility of modern electronic devices.
FAQ about Interface - Analog Switches, Multiplexers, Demultiplexers

1. What is an analog multiplexer?
An analog multiplexer is a device that can receive multiple input signals and combine these signals into one output signal according to certain rules. It combines multiple signals into one signal through a shared medium, thereby realizing signal multiplexing transmission. Analog multiplexers are widely used in communication systems, especially in television and radio transmission, where multiple signals are combined according to frequency division through frequency division multiplexing technology, and then transmitted through shared channels.
What is the difference between a multiplexer and an analog switch?
The main differences between a multiplexer and an analog switch are application scenarios, number of channels and signal processing capabilities.
Application scenarios and number of channels
Multiplexer: Mainly used in applications with a large number of channels, such as 4:1, 8:1, 16:1, etc. It can receive multiple input signals and synthesize a single output signal in a predetermined order, which is suitable for scenarios where multiple signals need to be processed simultaneously.
Analog switch: Mainly used in scenarios with a small number of channels, such as SPST (single pole single throw), SPDT (single pole double throw), etc. It is mainly used for channel selection or gear switching, and is suitable for scenarios where each channel needs to be controlled separately.
Signal processing capabilities
Multiplexer: It can process multiple input signals at the same time, divide each input signal into a series of time slices through time division multiplexing (TDM) technology, and transmit them in sequence. It requires high accuracy and stability to ensure accurate data transmission and low bit error rate.
Analog switch: Mainly used for channel selection, it cannot turn on multiple channels at the same time. The switch state of each channel is independent, which is suitable for scenarios where each channel needs to be controlled separately.

2. What is the difference between an analog switch and a digital switch?
Difference between analog switches and digital switches: 1. The function of an analog switch is to transmit analog signals. Since digital signals are also composed of two analog voltages from high to low, analog switches can also transmit digital signals; while digital switches mainly refer to MUX. 2. The signal current of a digital switch gate usually does not reach the output end; while an analog switch refers to a switch similar to an actual switch, whose signal current flows through the input end to the output end.

3. What are multiplexers and demultiplexers used for?
Multiplexers and demultiplexers are mainly used for sharing communication channels and data transmission.
Multiplexer (MUX)
A multiplexer (MUX) is a device that is able to combine multiple input signals into a single output signal, thereby transmitting multiple data streams on a single communication channel. Its main functions include:
Signal merging: Combine multiple input signals into one output signal for transmission over a single communication channel.
Frequency division multiplexing (FDM): In frequency division multiplexing, the spectrum is divided into multiple logical channels, each user occupies one channel exclusively, and the signal is modulated onto a different carrier frequency.
Time division multiplexing (TDM): In time division multiplexing, time is divided into multiple time periods, each time period is assigned to a different signal, and is usually used for digital communications.
Demultiplexer (DeMUX)
Demultiplexer (DeMUX) is the opposite of multiplexer. It decomposes the received composite signal into multiple output signals, each corresponding to an original input signal. Its main functions include:
Signal decomposition: Decompose the composite signal into multiple output signals, each corresponding to an original input signal.
Frequency division multiplexing (FDM): At the receiving end, the demultiplexer separates the composite signal into signals of each frequency, and then transmits them to the corresponding users respectively.
Time Division Multiplexing (TDM): At the receiving end, the demultiplexer separates the composite signal according to the allocation of time periods to ensure that the signal in each time period is correctly transmitted.
