Optoisolators - Logic Output are used in electronic devices to provide a means to transfer a signal from one side of a circuit to the other without actually having the two circuits connected to each other. A 6N134#300, which is usually described as a logic output optoisolator, is a semiconductor optoelectronic component used to isolate two electrical networks from one another.

Intro to the 6N134#300

The 6N134#300 optoisolator is an 8-pin device with a central LED optically coupled to a phototransistor. It is classified as a logic output optoisolator, providing electrical isolation between two sides of a circuit, with the LED part of the circuit on one side and the phototransistor on the other. The LED part of the circuit contains a photodiode that converts incoming light to an electrical current. The phototransistor receives the converted electrical current and functions as a switch or transistor. This logic output operates the input and output side of the optoisolator.

Application Field

The 6N134#300 is commonly used in applications that require a logic and digital-controlled output, such as relays, switches, and digital-to-analog converters. It is used in cases where electrical isolation is necessary between the input and output sides of a circuit. In addition, it is also used in memory-modifying applications, such as signal-conditioning and LED drivers. The 6N134#300 has also been used in communications systems, such as infrared communication, radio modems, and digital telephones.

Working Principle

The 6N134#300 operates in two different states. When the input on the LED side is activated, the optoisolator will be in the active (on) state. In this state, the electrical current sent by the LED will be switched on and will result in a logic output on the phototransistor side. When the input is inactive (off), the optoisolator will be in the inactive (off) state. In this state, the LED will not send current and the phototransistor will be off. In both the active and inactive states, the optoisolator provides electrical isolation between the two circuits.

Conclusion

The 6N134#300 is a logic output optoisolator that is widely used in various applications where electrical isolation is needed. Its operation is based on the emission of a current from the LED portion of the circuit when the input is activated, resulting in a logic output on the phototransistor. This optoisolator serves as a great way to transfer signals from one side of a circuit to the other in a reliable and electrically isolated manner.
