6N138
The 6N138 is an optocoupler, also known as an opto-isolator, which is a component used in electronic circuits to transfer electrical signals between two isolated circuits by using light. It consists of an infrared LED (light-emitting diode) on one side and a photodetector (such as a photodiode or phototransistor) on the other side, separated by a transparent barrier to ensure electrical isolation.
The 6N138 optocoupler is specifically designed for high-speed applications and is commonly used in various industrial, automotive, and communication systems where electrical isolation is necessary to prevent interference or to ensure safety. It provides reliable signal isolation and can handle relatively high data rates compared to some other optocoupler models.
