Optoisolators - Logic Output is a type of electronic equipment that use optical isolation principles to protect circuit components from voltage or current surges. There are many applications for this type of technology, including the FOD2200SDV. The FOD2200SDV is an optically isolated, logic output, digital optocoupler from Fairchild Semiconductor.

The FOD2200SDV has a wide range of applications including memory protection, logic isolation and level shifting. This application field enables the coupling of a logic signal output from one circuit to another. It isolates low-power logic systems from the harsh environment of industrial I/O applications. When used in conjunction with specialized protective logic, the FOD2200SDV provides reliable protection for industrial and automotive wiring systems from damaging voltage surges or currents.

In terms of working principle, the FOD2200SDV uses short light pulses to pass digital signals between two circuits that are optically isolated from each other. It has a transfer rate of 2 MHz and a propagation delay of 20 ns. This makes it suitable for many high-speed applications. A 650 nm LED emitting light is coupled to an integrated phototransistor in the device and it is driven by VCC. When the LED is activated, the light is detected by the phototransistor and a logic output signal is generated. The received signal is inverted logic between the phototransistor output and the output driver of the FOD2200SDV.

The FOD2200SDV also has innovative features which improve the isolation performances and safety of the device. It has a metallic baseplate which reduces the risk of an electrical failure due to heat dissipation. The device also uses high-quality components throughout its construction and an advanced driving algorithm which is tailored for high-speed signal transmission. Additionally, the FOD2200SDV has been designed to support a wide range of voltage supply levels. This provides a higher level of control over the system, allowing for easier and more efficient programming.

The FOD2200SDV is a highly reliable, compact optocoupler for digital logic output applications that offers superior isolation performance and safety. Its transfer rate of 2 MHz, low propagation delay and wide range of supply voltages make it an ideal choice for high-speed and low-power applications requiring logic level isolation. It is also resistant to noise, voltage spikes and current surges, which allows for greater stability and reliability.
