<H2> Introduction </H2>The SJM190BXC is a high performance device with comprehensive features. It combines the functions of an analog switch, multiplexer, and demultiplexer in a single package. It offers outstanding switching speed, low leakage current, low on-resistance, and low power consumption. It is suitable for a wide range of applications, including for interfacing analog, digital and control signals. Additionally, it also has built-in protection against over-temperature, short-circuit, ESD, and reverse current. <H2> Application Field </H2>The SJM190BXC is mainly used to switch analog, digital, and control signals between two or more locations. It is used for a wide range of applications, including for input/output buffering, data transmission and reception, signal routing, signal mixing, and signal conditioning. It can also be used for filter-switching applications, such as digital audio Equalizers, program selector switches, and video switching devices. <H2> Working Principle </H2>The SJM190BXC operates according to the principle of a voltage-controlled switch. The device is constructed with two series-connected Metal Oxide Semi-Conductor Field-Effect Transistors (MOSFETs), and a control signal is applied to each MOSFET’s Gate terminal. When a signal is applied to one of the MOSFET’s Gate terminal, that transistor turns on, closing the switch. Similarly, when a signal is applied to the other MOSFET’s Gate, it turns on and the switch is opened. Depending on the type, the voltage-controlled switches can be either normally-open (NO) or normally-closed (NC).The SJM190BXC also has a multiplexer and a demultiplexer. A multiplexer is a switch that is used to connect multiple inputs to a single output. It can also be used to connect multiple outputs to a single input. A demultiplexer performs the reverse operation, allowing multiple outputs to be connected to a single input. <H2>Conclusion </H2>The SJM190BXC is an optimal device for a variety of analog, digital and control signal switching applications. It offers outstanding switching speed, low leakage current, low on-resistance, and low power consumption. Additionally, it has built-in protection against over-temperature, short-circuit, ESD, and reverse current. It operates according to the principle of a voltage-controlled switch, and also includes a multiplexer and a demultiplexer.
