What is a 6N134/883B Logic Output Optoisolator?

A 6N134/883B Logic Output Optoisolator is an optical–electrical–optical (OTO) device which is used to electrically isolate two circuits. This device comes in two packages, one for each type of optoisolator. The 6N134 version has a TTL type logic output at a voltage level of 5V, while the 883B version has a CMOS type logic output at a voltage level of 3.3V.

What is the Application Field of 6N134/883B?

The 6N134/883B Logic Output Optoisolator is well-suited for systems with a high common-mode transient-noise immunity, as well as in pulse transformer and gate-drive applications. It can also be used to connect digital systems composed of different logic families, as the logic outputs can be connected directly to CMOS or TTL input pins. This optoisolator has found widespread use in different industrial, consumer, automotive, and commercial applications.

What is the Working Principle of 6N134/883B?

The 6N134/883B works by isolating the circuits it connects through the use of an LED and a photosensitive transistor. The LED side of the component is connected to the input side of the digital circuit, and the transistor side is connected to the output. When the input is triggered, the LED emits a light signal which is picked up by the photosensitive transistor, which then triggers the output signal. The isolation between the two circuits is achieved through this optical connection.

What are Some Benefits of 6N134/883B?

The 6N134/883B provides notable benefits as an optoisolator as it allows for the connection of different logic families without any risk of ground loop impacts or high frequency transients. The isolation between the two circuits also helps reduce system noise, as well as helping protect the circuits from overload conditions. These optoisolators are also capable of working in extreme temperatures, making them ideal for use in harsh environments.

Conclusion

The 6N134/883B Logic Output Optoisolator is an ideal device for use in digital systems, providing electrical isolation between the circuits, as well as reducing system noise. It is also well-suited for high common-mode transient-noise immunity, pulse transformer and gate-drive applications. Finally, the optoisolator’s capability to work in extreme temperatures makes them useful in many industrial, consumer, automotive, and commercial applications.
