The HCPL-786J-500E is a high-accuracy single-channel optically-coupled logic transceiver from Avago Technologies. It is primarily used to convert logic signals from one interface to the other with an optical link maintaining electrical isolation. The HCPL-786J-500E is able to transfer signals at over 500 Mbps and provide up to 1500Vrms of channel-to-channel isolation. As a result, it is an ideal solution for when electrical noise, ground loops, and interference degrade digital signals.

The HCPL-786J-500E is most commonly used in industrial, communication, and medical applications requiring high-speed and low-noise analog transmissions such as robotic arm systems, industrial control systems, network switches, and ultrasound systems. It is often used to recover data or control signals from long stretches of cable or in environments that are subject to high levels of electrical noise or harsh environmental conditions.

In terms of performance, the HCPL-786J-500E has a low power consumption of 5.6mA from a single 5V logic supply and has reliable performance over a wide temperature range from -40°C to +85°C. It also has a widelink transmission distance of 220m over twisted-pair cable, mainly due to its low-noise transmitter driver and high-immunity input receiver.

The HCPL-786J-500E supports various transmission speeds, from 500 Mbps at 25 meters up to 250 Mbps at 220 meters. In addition, the HCPL-786J-500E can be used in a multipoint configuration, allowing up to four independent signal nodes to be connected to the same bus line.

The HCPL-786J-500E optically isolated logic transceiver also provides a high level of noise immunity through its Schmitt-Trigger buffers. This allows the HCPL-786J-500E to accurately filter out unwanted noise to the extent that it meets the requirements of industrial standards such as the IEC 61000-4-2 standard.

The HCPL-786J-500E is designed to work with a wide range of digital logic families such as CMOS, TTL, and LSTTL compatible logic families. The HCPL-786J-500E has an input voltage range of -0.3 to 6V, which allows it to be used in a wide range of applications.

The HCPL-786J-500E operates in two modes: in the "open" mode the output is enabled when the input is above the threshold voltage (also known as active low), and in the "close" mode the output is enabled when the input is below the threshold voltage (active high). In either mode, a noise spike greater than or equal to 10ns can cause the output to switch.

The working principle of the HCPL-786J-500E is simple. An LED is used as the transmitter and an Phototransistor is used as the receiver. This allows the device to maintain electrical isolation between the input side and output side of the circuit, while still allowing digital signals to be transferred with minimal signal loss. The LED of the transmitter emits a beam of light that is transmitted across the optical link to the phototransistor on the opposite side. The phototransistor then converts the light into an electrical signal and the logic state of the signal is then transferred to the output.

The HCPL-786J-500E is an ideal solution for applications where electrical isolation and high-speed analog transmission is required to ensure reliable signal transmission. It is also able to provide a high level of noise immunity and low power consumption, making it well suited for industrial, communications, and medical applications.
