OPI1290-040

Optoisolators are used to transfer electrical signals and protect circuits from a wide range of environment and noise. The most commonly used type of optoisolator is the logic output device, which provides reliable and physically isolated electronic signals between input and output. These devices feature a phototransistor, or a solid state optically isolated gate, that allows control of air gap switches or devices on the output side of the optoisolator for a variety of applications.

The OPI1290-040 is a logic output optoisolator device, which has a low forward voltage requirement, maximum of 20mA forward current, and a switching speed of less than 100ns. It is an ideal device for applications such as high speed interface signals, used in computers, communication systems and other electronics requiring quickly switching outputs.

The OPI1290-040 device works on the principle of a transistor and a light emitting diode (LED). The transistor is connected to a power source and it is triggered by a signal from a light emitting diode (LED). When the LED is illuminated with an electric current, it causes a voltage spike in the transistor. This voltage spike causes the transistor to conduct the current to the output circuits, allowing the power to be transferred across the optoisolator without direct electrical contact. The LED is photodetectable, so any changes in the light intensity of the LED is detected by the transistor. This change causes an electric current to flow through the LED, which can be used to power the output circuit.

The OPI1290-040 is a great choice for a wide variety of interface applications, data communications, solid-state relays, computer memory control, as well as industrial, motor, transmission, and instrumentation systems. This optoisolator is an ideal choice for applications requiring high speed and low forward voltage, such as computer-controlled systems, communication systems, and other electronics that require a quickly switching output. It is also useful for applications such as circuit protection, circuit isolation, and stabilization of current/ voltage.

In summary, the OPI1290-040 is a logic output optoisolator device with a low forward voltage requirement, a maximum forward current of 20mA, and a switching speed of less than 100ms. This device is used to provide a physical isolated electronic connection between input and output circuits, which is useful for a wide variety of interface applications, data communications, solid-state relays, computer memory control, industrial, motor, transmission, and instrumentation systems. It is an ideal choice for applications requiring high speed and low forward voltage, such as computers, communication systems, and other electronics that require a quickly switching output.
