Optoisolators are a type of communication interface that has been designed to provide electrical isolation for both transmitters and receivers in applications where data, signals, and/or power have to travel between circuits. The advantages of optoisolators are numerous, but the main benefits include improved noise immunity; reduced electrical risks such as ESD or ground loops; and increased data security. The HCPL-2611-560E is part of the family of optoisolators, specifically those with logic output.

Technology and Specifications
The HCPL-2611-560E is a high-performance optocoupler featuring a logic output, packaged in a 16-pin DIP. This part operates on a wide range of operating temperatures, from around -40C to +85C. The HCPL-2611-560E also features an internal clamping diode for the logic output, which beats the possibility of dangerous, unwanted surge currents. This optocoupler takes in electrical and digital inputs at a common power supply of 4.5V to 24V, then outputs a logic level of 0 or 1 accordingly. It also features a high-speed 5ns response time.

Application Field
The main application fields for the HCPL-2611-560E Optoisolator include: digital logic interfaces, data transfer interfaces, and damage protection circuits. In digital logic interfaces, this device can provide electrical isolation between two systems exchanging data, for example, between an embedded device or computer and the logic level application. In data transfer interfaces, the HCPL-2611-560E can provide electrical isolation between two systems exchanging devices control signals like modes, pausing, and reset functions. Damage protection circuits can be used when there is a need to protect two circuits from each other, for example a motor controller circuit and a logic circuit.

Working Principle
At the heart of the HCPL-2611-560E is an LED light source and a phototransistor, which are arranged in an optocoupler package. The LED produces light, typically infrared, of a specific wavelength, for example 1.1 um. When an electrical signal is applied, the LED emits light which strikes the phototransistor, which in turn amplifies the signal and outputs it as a logic level of either 0 or 1 accordingly. The amplified logic level is then interpreted by the user’s device.

The HCPL-2611-560E optocoupler provides an electrically isolated interface between two circuits. This allows for improved noise immunity and data security, as well as providing better protection from electrical risks such as ESD and ground loops. The HCPL-2611-560E offers a wide range of operating temperatures, a high-speed 5ns response time, and an internal clamping diode for safer operation. This optocoupler is suitable for digital logic interfaces, data transfer interfaces, and damage protection circuits. It can provide electrical isolation between two systems exchanging data, enabling improved noise immunity and data security.
