Optoisolators, specifically logic output optoisolators, are designed to protect and protect circuits from electrical noise. The logic output optoisolator is used in the isolation of digital signals for industrial and in scientific and medical devices. The FOD8160R2V, by Fairchild, is one of the most commonly used optoisolators to provide this type of isolation.

The FOD8160R2V is a slotted type, 1000V optical-coupler with a built-in Schmitt trigger and a data sinking output. It is a 3.3V logic gate output, with a 4-pin DIP configuration and a low-voltage gain. The device has a pair of output collectors with a minimum 1.0mA drive current, a high-voltage isolation of 10,000 Vrms and a minimum of 1,000Vrms, with a maximum surge of 4,000Vrms.

TheSchmitt trigger input circuitry ensures that the optical-coupler is resistant to voltage spikes and counter-electromotive force, as well as to slow input signals. This results in less data loss when used in noise-sensitive applications. With its 4-pin DIP configuration and low voltage gain, the FOD8160R2V is easy to incorporate into many existing designs.

The main applications for the FOD8160R2V are in industrial applications, medical and scientific equipment, computers and peripherals, and communications. Its low-voltage gain and its Schmitt trigger input circuitry make it suitable for use in noise-sensitive environments where data integrity are important. It is also well suited for high-speed operation, such as in bus interfaces, where it prevents AC interference as well as DC interferences.

The working principle of the FOD8160R2V relies on the fact that electrical signals can be transmitted without making physical contact. This is accomplished through the use of an optocoupler, which consists of an infrared LED or an infrared light-emitting diode, and a phototransistor. When the LED is activated, it emits light that is focused onto the phototransistor. The transistor is triggered, amplifying the light signal and sending a logic level signal to the output.

In the FOD8160R2V, the Schmitt trigger input circuitry serves to improve the trigger threshold of the optoisolator so that it provides a greater level of immunity to slow and/or noisy input signals. It also helps to prevent false triggering of the output. This is an integral part of how the FOD8160R2V works and enables it to work effectively in noise-sensitive applications, such as in bus interfaces where data integrity is important.

The FOD8160R2V is an excellent optoisolator for industrial applications, medical and scientific equipment, computers and peripherals, and communications, due to its low-voltage gain and its Schmitt trigger input circuitry. It is capable of providing a high-level of noise immunity and also prevents false triggering of the output, making it ideal for use in noise-sensitive environments where data integrity is critical.
