Optoisolators are optoelectronic components designed to electrically isolate one circuit from another. They have been widely used in many different fields in the past few decades. One of the most commonly used types of optical isolators is the HCPL-560K #200, which is a type of optoisolator that incorporates a logic output. This article will discuss the application field and working principle of the HCPL-560K #200.The HCPL-560K #200 is a high performance logic output optoisolator, which isolates logic levels between two circuits. It provides a safe, reliable electrical barrier to protect microprocessor systems and other sensitive digital equipment from high voltage spikes, as well as providing ESD protection. In addition, the HCPL-560K #200 is compatible with 3.3 to 5.5 V logic families, and can be used with a wide range of logic families.The HCPL-560K #200 is designed for use in a variety of applications, including interfacing between RS-485 and I2C buses, motor control, and power switching. It can also be used for level detection and logic signal conversion. The HCPL-560K #200 is ideal for use in almost any embedded application, and is particularly suited for use in medical, automotive, and industrial automation applications.The HCPL-560K #200 features an integrated LED driver, a phototransistor output transistor, and a hysteresis resistor. The LED driver has a high switching speed of 500000µs, and a low propagation delay time of 125µs. The phototransistor output transistor features a high gain of 1024V/µA, and a low input current requirement of just 1µA. The hysteresis resistor provides extra noise protection, and it also ensures that the output is not affected by logic level noise.In operation, when the input logic level is driven to a high level, the LED driver will turn the LED on, which in turn will activate the phototransistor and allow a current to flow through the hysteresis resistor. This causes the output of the optoisolator to switch to a high logic level. When the input logic level is driven to a low level, the LED will be turned off, preventing current from flowing through the hysteresis resistor and causing the output to switch to a low logic level.The HCPL-560K #200 is a powerful and versatile optoisolator that provides a safe and reliable way to isolate logic signals between two circuits. It is well-suited for use in a variety of embedded, medical, automotive, and industrial automation applications. Its fast switching speed, low propagation delay time, and high gain make it ideal for interfacing between RS-485, I2C buses, and other logic families. The HCPL-560K #200 also provides excellent noise immunity, helping to ensure that the output of the optoisolator is not affected by logic level noise.
