Optoisolators are electronic components that allow a circuit to operate at different voltage levels, with one circuit isolated from another. The device type used in this application is SFH6720-X001T. It can be used to provide digital isolation with high switching speed, while isolating the signal from any EMI.

Optoisolators are used for many applications in different industries; however, in this application, the SFH6720-X001T is designed for isolation of logic low signals with a low power consumption and high switching speed.

SFH6720-X001T features a high switching speed of up to 600 Megabits per second, which is especially beneficial for digital video applications. In addition, the optoisolator offers a very low power consumption of only 250mW. This makes it very useful for hot-swapping applications, where the components must be able to walk into and out of a system without the need for power cycling.

The SFH6720-X001T optoisolator uses an LED and a photosensor structure to achieve isolation. The LED transmits light, which is then picked up by the photosensor. This input signal triggers a transfer of information, and the device will activate if the data is correct. The input to the LED is a digital signal which is converted from the logic high or low signal. On the receiving side, the photosensor will detect the optical signal from the LED and convert it into a logic low or high signal. This is how the logic low signals are isolated between two circuits.

What makes the SFH6720-X001T optoisolator so useful is that it provides superior noise rejection. This is achieved through the addition of three pins – VCOM, COM, and GND. These pins act as reference points for the signal, and the device will not respond to any signal that is not the expected voltage level. This reduces the risk of false readings, and makes the device suitable for high reliability applications.

In addition, since the SFH6720-X001T works without direct contact between the two sides, there is no need to worry about electrical contact or corrosion. This increases the reliability and the lifetime of the device, and makes it ideal for many different applications.

Overall, the SFH6720-X001T optoisolator is an ideal solution for many digital low logic applications. It offers excellent performance, low power consumption, and superior noise rejection, making it particularly useful for data transmission applications.
