The HI-8191PSIF is an interface device with analog switch, multiplexer, and demultiplexer characteristics. It is a versatile device with a number of application fields including signal isolation/signal conditioning, triggering, and level shifting. This article will discuss the important application field and working principle of HI-8191PSIF.
Applications and Functions
The HI-8191PSIF is designed for precision bi-directional signal switching and signal level conversion. Its application fields include analog signal isolation and signal conditioning, triggering, and level shifting. The device offers high performance and low power consumption, making it suitable for use in a variety of industrial control and instrumentation systems.
The HI-8191PSIF can be used as an analog switch, multiplexer, and demultiplexer. It allows a bi-directional signal line to switch between two input signal sources (one with a higher voltage than the other). This device can also be used to convert the input signal to a lower voltage output without introducing any distortion or noise. In addition, it is capable of transferring high voltage levels up to 45V in a single lane while still offering excellent signal isolation.
Working Principle
The HI-8191PSIF integrates an analog switch, multiplexer and demultiplexer. It utilizes a P-channel and an N-channel MOSFET switch to provide electrical switching. The device also incorporates an internal voltage reference for level shifting. The P-channel and the N-channel MOSFETs are individually controlled by separate control inputs, allowing the user to easily select an input signal source or convert an input signal to a lower voltage.
The P-channel MOSFET controls the N-channel switching and the N-channel MOSFET controls the P-channel switching. When the P-channel is enabled, the N-channel is disabled and vice versa. When both MOSFETs are enabled, the HI-8191PSIF provides a direct connection between two signal lines without any level shifting. Once the N-channel MOSFET is disabled, the input signal is level shifted to the output signal line according to the internal reference voltage.
The device provides excellent signal isolation that meets industrial standards. It is specifically designed to withstand extreme conditions such as high temperature, high pressure, and long time periods. In addition, the device offers a wide range of power supply voltages from 3.3V to 32V, making it suitable for many industrial applications.
Conclusion
The HI-8191PSIF is a versatile device that covers many application fields such as signal isolation/signal conditioning, triggering, and level shifting. Its ability to switch between two input signal sources and to provide exquisite level shifting provides users with the flexibility needed for efficient and effective integration. Furthermore, its low power consumption and wide range of power supply voltages make it an ideal choice for industrial control and instrumentation systems.
