Optoisolators are isolators used to bridge electrical connections between two circuits while keeping them physically isolated. If two circuits must communicate, but there is risk of a potential difference between the circuits, optoisolators are used to ensure no damage is done. This type of isolator can be identified by looking for a logic output in the form of an LED. The LED in this circuit emits a light when current passes through it which triggers current in the opposite circuit. The LED operates as an output, while the opposite circuit receives the signal via its phototransistor. One example of this type of application is the H11L1FVM Optoisolator.

The H11L1FVM isolated logic output optoisolator consists of an infrared LED and NPN Darlington phototransistors in a 6-pin DIP package. It has a working frequency of up to 10MHz and has an isolation voltage of 5.7kV RMS. It is designed to provide levels of isolation to protect both input and output circuit logic, allowing them to be connected via an isolator without the need for ground line potential isolators, or creating a barrier between them. It is often used in communication networks, industrial instrumentation, medical systems, and other high-frequency applications.

The working principle of the H11L1FVM Optoisolator is based on the use of an LED and phototransistor to form an isolator between two circuits. This isolator uses the LED to transmit light when the input voltage is applied, which triggers the optical signal in the opposite circuit. This in turn triggers its own phototransistor, which responds and emits an effective output signal in the form of a switching action. This isolator requires no external power source and the signal remains in an effective and stable manner over a wide range of temperatures.

The advantages of using the H11L1FVM Optoisolator include its high isolation voltage, fast response time, and low power consumption. It is also important to note that this isolator is effective for noise suppression in RF applications, and is highly reliable. This optoisolator can also be used for higher speed communications as its logic output is capable of frequencies up to 10MHz. Last but not least, the H11L1FVM’s packaging and size make it suitable for use in a variety of applications.

In conclusion, the H11L1FVM Optoisolator has a range of features and capabilities that make it ideal for use in a variety of logic output applications where high levels of isolation are required. It is reliable in operation and offers low power consumption, fast response times, and a wide operating temperature range. Its ability to handle high-frequency signals up to 10MHz makes it an effective choice for many communications networks and other specific industrial instrumentation related applications.
