Optoisolators, also known as Optocouplers, are electrical components designed for isolating electrical connections between two circuits. They consist of a light-transmissive optically-coupled isolation barrier between one or more light-emitting diodes (LED) and one or more photodetectors. Among multiple types of optoisolators, the HCPL-2231-500E model belongs to Logic Output Optoisolators. Its application field and working principle are discussed in this article.
Application Field
The HCPL-2231-500E optoisolator is designed for logic signal transfers between two circuits. It features a miniature PCB package ideal for industry-standard TTL logic gate outputs. This optoisolator also comes with input-to-output electrical isolation feature that provides reliable signal isolation between different circuits, which is useful for applications that require a high degree of electrical isolation.This optoisolator is designed for a variety of applications, such as digital input stage of logic gates, logic level shifters, and pulse signal pick-ups, among others. It also comes with surge protection and low-power consumption, making it a reliable choice for any logic signal transfer application.
Working Principle
The HCPL-2231-500E optoisolator uses a single gallium arsenide infrared LED as an optical transfer component, which is surrounded by an integrated photodetector. The LED sends out an optical signal, which is then received by the photodetector, thus creating an electrical signal.The electrical signal is isolated from the LED layer via the integrated photo-diode. This means that any electrical noise generated by the LED will not affect the signal transferred by the photodetector. The LED can draw current from the circuit output, which is then used to drive the LED.
Conclusion
The HCPL-2231-500E optoisolator from Optoisolators applies isolation between two circuits, allowing for reliable electrical signal transfer. With its miniature PCB package, low power consumption, and surge protection, the HCPL-2231-500E is a great choice for a variety of application fields, including digital input stages, pulse signal pick-ups, logic gate outputs, and more. Furthermore, its single LED and integrated photodetector allow for clean, optimized signal transfer with superior electrical noise protection.
