Optoisolators, also known as optical isolators, are a type of interface device that use light-emitting components such as LEDs to provide isolation between two electrical circuits. The 6N134 is an individual optoisolator IC with an open-collector logic output. It offers very low control current requirements, low-power consumption, low-noise operation, and low cost.

The 6N134 features a phototransistor output with a motorized-drive speed of 50 mA. The typical quiescent current of the device is just 1 µA when the LED is off, which helps to reduce power consumption. It also has a fast response time of 20 ns from its forward direction and a slow response time of 40 ns from its reverse direction, providing a diverse range of applications.

The 6N134 is well suited for low-voltage logic applications in various medical, industrial, and consumer electronics, such as in temperature, pressure, and flow sensors, as well as medical and automotive equipment. It is also suitable for low-power applications in which the high-speed switching characteristics are not essential. Such applications include signal conditioning for process automation, building management systems, and gas and flow measurement.

The 6N134’s working principle is based on the optocoupler effect. When the LED within the 6N134 is excited by an input voltage, photons are emitted from the LED and strike the phototransistor contained in the package. The phototransistor is then triggered, resulting in a change in the current flowing from the output, which activates the logic. Thought the optoisolator effect, the output is completely isolated from the input, and the user can be assured of the signal’s galvanic isolation and ruggedness.

The 6N134 is one of the latest optoisolators in the market, offering a combination of performance, reliability, and affordability unlike any other. By leveraging its patented technology and design structure, the 6N134 offers the ultimate in low power consumption, fast response time, and high signal quality. With its low-voltage logic output and multiple current output options, the 6N134 is sure to become a popular choice for a wide array of industrial, medical, and consumer applications.
