Optoisolators - Logic Output, often known as H11N1SM, are electronic components used to provide electrical isolation between two separate circuits. They are used to protect microprocessors and other sensitive electronics from environmental factors that could cause electrical noise, such as lightning or static electricity. The basic component of an H11N1SM is a light-emitting diode (LED) connected in series with a photovoltaic diode (PV). When the LED is energized, it will emit a beam of light that is then detected by the PV, which in turn generates a voltage that is used to activate the logic circuit. The basic principles of operation of an optoisolator are demonstrated in Figure 1.

The operation of the logic output optoisolator is based on two basic principles. First, an LED is used to provide the input to the device, and a PV is used to provide the output from the device. The LED is connected in series with the PV, such that when the LED is energized, the current passing through the LED is detected by the PV. This current causes the PV to generate a voltage that is used to activate the logic circuit. The circuit is usually activated or deactivated by the application of a voltage signal to the LED.

The second principle of logic output optoisolators is the use of a voltage-level shifter. This device works by converting the voltage generated by the PV to the appropriate logic level for the logic circuit. When the logic circuit is activated, the voltage shifter will convert the voltage generated by the PV into a logic level that can be used by the logic circuit. This allows for the use of logic circuits with different voltage requirements. The voltage level shifter can also be used to perform signal isolation, which is useful in applications such as medical instruments, where the processor needs to be protected from the environment.

Optoisolators with a logic output can be used in many different application fields, from industrial to consumer electronics. Industrial applications include signal isolation, switch and sensor control, motor control, and motor speed control. In consumer electronics, optoisolators are used in data communications, including Ethernet, USB, and FireWire. They are also used in audio processing, such as in loudspeaker and microphone systems.

Optoisolators with a logic output are an important component of many systems. The use of optoisolators allows for the isolation of sensitive electronics from the environment, which can prevent damage to the electronics due to lightning or static electricity. In addition, the use of a voltage-level shifter allows for the use of logic circuits with different voltage requirements, and can also provide signal isolation in applications such as medical instruments. As such, optoisolators with a logic output are an important component of many systems.
