Optoisolators – Logic Output is an important component used for transferring signals between circuits of mutually incompatible voltages while maintaining the integrity and safety of the circuits. The ACPL-K64L-560E is one such component. This application report provides a detailed explanation of the ACPL-K64L-560E’s application field and working principle.

Application Field

The ACPL-K64L-560E is an optoisolator with logic output. It can be used for controlling the voltage difference between two circuits and also for isolating circuits of different voltages. It is mainly used in the following two scenarios.

• It can be used for converting signals from various sources into logic outputs. For instance, it can be used for converting level signals, pulse signals, square wave signals and other analog signals into digital signals. Thus, the logic output optoisolator allows the user to control the signals of different sources in a more efficient manner.
• Apart from signal conversion, the logic output optoisolator can also be employed to isolate two circuits connected together. The logic output optoisolator helps maintain the isolation between the two circuits and ensures that no current passes from the one circuit to the other. This allows for safer operation of the components.

Working Principle

The working principle of the ACPL-K64L-560E is quite simple. It uses an infrared emitter and a photodetector on either side of the optoisolator. The infrared emitter provides a light source which is in turn detected by the photodetector present on the other side of the optoisolator. Whenever the light source is interrupted by any means, the photodetector senses the interruption and sends a signal to the output. Thus, when a signal is applied to the input of the logic output optoisolator, it is converted into a logic output depending upon if the light source is on or off.

The ACPL-K64L-560E can also be used to identify whether an external signal is present or not. In this case, an external signal is applied to the input and corresponding logic signal is sent to the output depending on the presence or the absence of the signal. This is useful in cases where the user needs to detect a certain condition in a circuit.

The ACPL-K64L-560E is equipped with several features which make it suitable for a variety of application fields. These include a wide operating temperature range of -40°C to 85°C and a wide dynamic range of 0.5mA to 10mA. Moreover, the optoisolator is provided with a built-in Zener diode for adjusting theLED current and a fail-safe circuit to protect the internal circuitry in case of a short circuit.

In conclusion, the ACPL-K64L-560E is a logic output optoisolator that is designed to convert signals from various sources into digital signals and/or to isolate two circuits connected together. It is equipped with several features that make it suitable for a variety of applications. Furthermore, the working principle of the device is quite straightforward and is an important tool for all kinds of signal conversion and isolation tasks.
