Optoisolators are used for electrical isolation, input/output isolation, signal transmission, and secure data communication. They can also be used as an optocoupler, acting as an intermediary between two pieces of circuitry to protect one from the other. An optoisolator, or optocoupler, is a device which consists of a light-emitting diode (LED) and a phototransistor. The HCPL-263L-520E, produced by Avago Technologies, is an optoisolator specifically designed for logic output applications.
The HCPL-263L-520E optoisolator assists in signal transmission and transmission protection required when connecting two separate systems. The device achieves electrical isolation with a interposing safety gap between the input and output circuits. The LED and phototransistor within the device join together via an optically coupled junction, providing high interface stability and a long life span due to no direct electrical connection between the two circuits. The optoisolator further helps to prevent noise from being introduced into the circuit, and helps to protect the circuitry being connected from being overloaded.
The HCPL-263L-520E optoisolator comes in a molded plastic surface mount package. The device operates over a temperature range of -40°C to 85°C. The I/O LED current is specified for 10 mA max. The high current LED allows this optoisolator to switch faster than other optoisolators and improve the performance of the system.
The HCPL-263L-520E works by allowing the LED to emit a signal to the phototransistor. The phototransistor then amplifies the current, changing it from a logic 0 to a logic 1, or vice versa. This allows for basic on/off control of the input circuit. The LED is powered from the input side of the optoisolator, while the output side is powered from a separate source, allowing for data transmission between the two circuits.
The HCPL-263L-520E logic output optoisolator provides an effective way of controlling voltage sensitive components. The device is generally used for operation of high power solenoids, relays, motors, and other components which need to be operated remotely or electrically isolated from the on/off signal switch. The device can also be used in audio/video switching applications, providing an isolation barrier between the source and destination. The optoisolator further allows for controlling current signals, without affecting the actual voltage supplied to the destination.
The HCPL-263L-520E operates at a lower cost, compared to other optoisolators, while providing the same level of signal isolation and protection. This can enable system designers to use the device in a wide variety of applications. The input/output circuit of the optoisolator can also be easily connected, without the need for much wiring. The device is relatively straightforward to use, and requires no preliminary adjustments or maintenance.
In conclusion, the HCPL-263L-520E optoisolator is suitable for applications requiring a logic output, such as signal transmission and transmission protection. Its small plastic surface mount package enables for easier circuit integration and efficient protection. The two circuits which are coupled by the device are electrically isolated, while the LED current output allows for faster switching performance. The device requires no maintenance or prior adjustments and helps provide an optocoupler with an operational life span of years.
