Optoisolators – Logic Output is a technology used in many applications. One of the most popular and versatile technologies is the HCPL-543K#200 Logic Output. This optoisolator is designed to provide high speed and high accuracy logic signal inputs and outputs for both digital and analog applications in a wide range of applications. It features a totally isolated output, meaning that it will not affect other circuits despite providing a fast and accurate output.

The HCPL-543K#200 utilizes digital logic and Infrared (IR) technology to provide a robust, secure and low-cost solution for applications involving circuit isolation, switching, logic, and protection. The optoisolator is equipped with a light-reeving attenuator (LRA) and a dampening screw. The LRA is used to reduce the light intensity of the optoisolator’s input signal and ensure its accuracy. The dampening screw helps reduce any noise generated by the optoisolator when the signal is being transferred.

The HCPL-543K#200 optoisolator is most commonly used in industrial automation, automotive, medical and consumer electronics, military and aviation, office equipment, gaming, and other safety-critical applications. This device is designed to offer reliable and accurate logic signals with low noise in a wide variety of environments and applications. Because of its versatile design, the HCPL-543K#200 is an ideal solution for signal protection, noise immune logic control, high speed signal switching, and high frequency signal transmission.

The HCPL-543K#200 operates on the concept of coupling, where electrical energy is transferred between two isolated circuits using light. The optoisolator uses Infrared (IR) light to transfer the signal from the circuit board to the optoisolator. The output signal is then converted to electrical energy with a light sensitive switching device known as a photodiode. This photodiode is protected by a special material and can provide the required isolation for analog signals.

The optoisolator can provide logic outputs from 0.2 V to identify a logic high and 0.0 V to identify a logic low with 5 volts. The optoisolator is equipped with provisions for open-collector or open-drain outputs. This allows the signal to be transmitted across a wide range of temperature and voltages without affecting the signal quality. The device is also designed to reduce power consumption by providing a minimum hold current, enabling low power operations.

The HCPL-543K#200 optoisolator is an Industry Standard Transistor-Transistor Logic (TTL) Open-collector Logic Out (OCLO) optoisolator. It utilizes a GaAs infrared LED to provide a fast and reliable transfer of digital data. The optoisolator is designed to provide a totally isolated output that ensures data integrity between two circuits. It is also designed to operate at a wide variety of temperatures, voltages, and frequencies making it ideal for a variety of applications.

In conclusion, the HCPL-543K#200 optoisolator is a reliable and versatile technology that provides a robust, secure and low-cost solution for signal transfer between two isolated circuits. It is ideal for a wide range of applications including industrial automation, automotive, military and aviation, medical and consumer electronics, office equipment, gaming, and other safety-critical applications.
