The PS398CSE Interface - Analog Switches, Multiplexers, Demultiplexers range is an advanced circuit protection solution used in a wide range of applications where reliable and high-performance circuit protection is of great importance. The main role of the family is to protect circuit components from overvoltages and undershoot events when switching on and off, and to minimise the risk of catastrophic failure. The PS398CSE operates in both the supply and ground domains and offers a wide range of protection attributes, such as leakage current, current limit, and a low current-on/current-off load. It also boasts excellent low impedance operation, good thermal performance and high protection limits.

The PS398CSE is designed with a three-level power shut-down system to ensure safe system operation. The topmost level of protection features dv/dt monitoring that shuts down the power supply when the dv/dt exceeds the preset limit. The second level of protection features overvoltage and undershoot monitoring that shuts down the power supply when the voltage exceeds the preset limit. The bottommost level of protection features current limit monitoring that shuts down the power supply when the current exceeds the preset limit.

PS398CSE\'s switches have the capability to transfer analogue signals between the primary and secondary side of the circuit without introducing noise to the analog signal. They can support switching operations between the primary and secondary side while maintaining low input capacitance, low output voltage drop, and high current levels. The integrated demultiplexer in the switch enables the circuit to be configured in a way so that only a specific part of the circuit is powered on while the rest is powered off.

The PS398CSE multiplexers have the capability to route different signals to different outputs depending on the state of the control signal. They can also be used to convert an analogue signal into a digital one for further processing. The multiplexer also offers protection against external and internal over voltage and overcurrent, high circuit loop and integrated surge protection. Furthermore, it supports partial powered on/off switching, which helps to reduce power consumption.

PS398CSE integrated multiplexers also feature low insertion loss and a high level of isolation, which help to ensure that there is no contamination of the analog signals in the system by preventing stray signals from being added to the circuit. The multiplexer has a high output-to-input ratio, which minimizes the effect of signal distortion on the overall system, and thereby helps to improve the accuracy of the circuit’s output. The multiplexer also boasts excellent cross-talk protection, which prevents adjacent signals from interfering with each other.

The PS398CSE demultiplexers are used to distribute multiple signals to multiple outputs. They can support routing of analogue signals and also can be used to convert digital signals into analogue ones. The demultiplexer also provides high impedance, low input and output voltage drops, and low leakage currents, helping to reduce power consumption. In addition, the demultiplexer features excellent isolation, which helps to reduce crosstalk between the different signals in the system.

The PS398CSE is a highly reliable and efficient range of interface - analog switches, multiplexers and demultiplexers that can be employed in a wide range of applications. It provides an economical, yet reliable, solution for circuit protection and signal routing in a wide variety of applications. With its extensive range of features, it is ideally suited for use in challenging industrial and automotive settings, where reliable and robust circuit protection is of paramount importance.
