Optoisolators - Logic Output

Optoisolators, also known as optocouplers, are devices that are equipped with two separate electrical systems in order to provide electrical and optical isolation between them. This means that the elements within these two systems can interact, but will be optically isolated from each other to prevent any kind of electromagnetic interference or ground loop effect. Optoisolators, like the 6N137S1(TB), are often used in logic and analog applications due to their ability to provide a way to transfer signals between two different circuits while still providing electrical and optical isolation.

6N137S1(TB) Application Field and Working Principle

The 6N137S1(TB) is a logic output optoisolator designed for general purpose applications. It is designed to provide reliable electrical isolation between two circuits while still transferring the logic signal. The optoisolator consists of an input photodiode, an optical isolator, output FETs and protection circuits, and a built-in output status indication LED. The input photodiode is connected to the logic control circuit and is used to detect and convert light energy into electrical energy, which is then converted into a logic signal. The optical isolator is used to ensure that no electrical current passes between the input and output circuit, providing electrical isolation. The coaxial FETs at the output are used to amplify the logic signal and the built-in protection circuits are used to protect the optoisolator from overloads and short circuits.

The 6N137S1(TB) is designed for use in general purpose logic applications, such as logic switches and inverters, and can be used in various analog applications, such as pulse circuits, signal converters, and frequency dividers. It can also be used in logic level conversion, interfacing logic systems to microprocessors, and driving relays or other output devices. The 6N137S1(TB) can be used in applications that require up to 5V logic signals, and the optoisolator has a very low (1.7mA) maximum operating current, making it a great choice for low power applications. The optoisolator also has a very fast switching speed, providing users with reliable and accurate logic signal transmission.

In conclusion, the 6N137S1(TB) is a high performance logic output optoisolator that is designed for general purpose applications. It is designed to provide reliable electrical isolation between two circuits, and is capable of handling up to 5V logic signals. The optoisolator has a very fast switching speed and low operating current, making it a great choice for low power applications. The optoisolator also has a built-in status indication LED which can be used to verify the status of the optoisolator.
