Optoisolators - Logic Output

The ACPL-071L-560E is an optoisolator logic output device manufactured by Avago Technologies. It is a low-cost, industry standard optoisolator designed for error-free transmission and reception of digital signals including DC and AC signals. In this article, we will discuss the application field and working principle of the ACPL-071L-560E.

Application Field

The ACPL-071L-560E is primarily used in electro-optic data transmission applications. It features a single digital input and a single digital output port, which simplifies the circuit design and reduces cost. It is also suitable for use in noisy environments, where it can filter out unwanted AC or DC voltage noise from the data transmission. The ACPL-071L-560E is also widely used in applications such as medical instrumentation, communication equipment, industrial controls, instrumentation, and automotive systems.

Working Principle

The ACPL-071L-560E is an optoisolator which utilizes optoelectronic components to electrically isolate a digital signal. These optoelectronic components work by converting an electrical signal into an optical signal. This optical signal is then transmitted to a receiver which converts it back into an electrical signal. The benefit of this optoisolator is that it keeps the transmitted and received signals electrically isolated, thus reducing the potential for electrocution and preventing short circuits. It also improves the signal integrity, as the optical signals are not affected by electrical noise.

The ACPL-071L-560E is composed of a transmitter LED, a receiver photo-diode, a signal conditioning circuit and a comparator circuit. The transmitter LED converts the input signal into an optical signal, which is then transmitted to the receiver photo-diode. The receiver photo-diode then converts the optical signal back into an electrical signal. The signal conditioning circuit conditions the signal, converting it from an analog signal to a digital signal, which is then sent to the comparator circuit. The comparator circuit then compares the digital signal to a threshold value and outputs either a low or high logic level, depending on whether the signal is above or below the threshold.

The ACPL-071L-560E is a highly efficient, low-cost optoisolator logic output device which is capable of transmitting digital signals in a wide variety of applications. By utilizing optoelectronic components to electrically isolate the transmitted and received signals, the ACPL-071L-560E can provide reliable, error-free data transmission in even the most demanding environments.
