Optoisolators are a type of electronic component used for isolating high voltage or high power circuits from low voltage control circuits. Widely used in industrial and automotive applications, optoisolators improve system reliability by creating an electrical barrier between two different parts of the system. The HCPL-0466-060E optoisolator is a high-performance logic output isolator used for a variety of applications.

The HCPL-0466-060E utilizes an 850nm AlGaAs LED input stage coupled with a high speed integrated Silicon Avalanche Photodiode (SiAPD) output stage. It is available in an 8 pin DIP package and is rated for operation over the -40°C to +85°C temperature range. The device has wide common mode transient immunity up to 250kV/μs and features improved CMR levels of up to 30kV/μs. This performance, combined with a CTR greater than 50% (min) at a specified LED current, pushes the HCPL-0466-060E to the forefront of logic output optoisolation technology.

The HCPL-0466-060E is designed to provide a signal path for non-isolated voltage switching of logic circuits. Its applications range from simple logic isolation to providing noise immunity in mixed signal systems. It is particularly useful in the protection of sensitive programmable logic controllers (PLC) against transient voltage signals. The optoisolator also finds use in AC/DC inverter and SCR thyristor control circuits for applications like motor speed control or battery charging.

For working, the HCPL-0466-060E optoisolator consists of two terminals; an input terminal and an output terminal. At the input terminal, an LED illuminates when a control signal is applied to it. The emitted light ray then strikes the output terminal photodiode which produces an electrical current. This current proportionally follows the signal. The stronger the output signal, the larger the current. The output terminal electrical current then switches the logic circuit in the same way as if the switch was connected directly to the input.

The HCPL-0466-060E optoisolator is well-suited for a variety of logic transfer applications. Its wide common mode transient immunity and improved CMR levels make it a reliable choice for protecting sensitive PLCs and other logic components against transients. Its fast light response time, low dark current and high CTR make it ideal for controlling motor speed and battery charging functions. Ultimately, this device is perfect for any application where reliable logic transfer is required.
