Introduction to Optoisolators - Logic Output

Optoisolators are electrical components which use light to transfer signals, helping isolate two circuits while keeping them electrically connected. This technology dates back to the 1940s, and since then, the technology has advanced greatly and there are dozens of models and types available. Optoisolators play a major role in crossovers between digital and analogue signals, logic and memory, and micro-controllers and embedded systems. Logic Output optoisolators are used to protect integrated circuits such as microprocessors. These devices use the single channel design and need input sources such as TTL, DTL, and compatible logic systems. The logic output optoisolators have a separate photo-coupler which isolates the parameters of the two circuits including voltage, current, noise, and radio frequency interference.One such device is the HCPL-260L-560E from Broadcom which stands out as it offers an additional level of circuit protection and a high low static current drain of .

HCPL-260L-560E Optoisolator - Overview

The Broadcom HCPL-260L-560E is a 500 mA logic output optoisolator with an output at 5V DC Load, suitable for use in periods of up to 5V DC. It offers high level of circuit protection against overvoltage and thermal damage, and it also has a static low current drain of 0.3 mA which minimizes power consumption from the logic circuitry. The isolation voltage is up to 2500 V rms which ensures reliable operation even under extreme environmental circumstances.The optoisolation technology used in the HCPL-260L-560E ensures improved overall stability and guarantees a high level of reliability. The device additionally incorporates an FCC compliant emitter architecture which helps reduce power consumption and guarantees minimum 1.5V level shifting.The HCPL-260L-560E includes an MB2545 electrically isolated collector output and requires an operating temperature of -40°C to 85°C. It also incorporates an open-collector optocoupler with a single channel design, and has a collector-emitter voltage rating of 80V .

HCPL-260L-560E Application Field and Working Principle

The HCPL-260L-560E optoisolator is used for general purpose digital to analog conversion as well as isolation of logic and output signals. The device is often used in microcontroller systems, logic systems, and embedded systems. These optoisolators are also suitable for use in various automated systems or industrial equipment that require significant protection from the surrounding environment.The basic working principle behind the HCPL-260L-560E optoisolator is that it consists of an LED and a photovoltaic transistor optically coupled to each other. When a signal is applied to the optoisolator\'s input, the LED is illuminated and drives the photovoltaic cell, causing an electrical signal to be generated. This electrical signal is then fed into the output isolation component, which is the waveform corresponding to the input signal. Therefore the device can safely isolate two circuits electrically while preserving their electrical link.
