HCPL-2611#020

Optoisolators are external devices used to provide isolation between two pieces of equipment, typically in a logic circuit. The HCPL-2611#020 is a logic output optoisolator, used to provide a logic link between two devices, and act as an insulator to protect from AC signals and electrical maladies. Below, we\'ll look at the application field and working principles of the HCPL-2611#020.

Application

The HCPL-2611#020 logic output optoisolator is typically used in applications where electrical isolation between two pieces of equipment is needed. This type of optoisolator is used in applications where it is necessary to ensure that noise or other signals do not cause the outputs of the equipment to interfere. The HCPL-2611#020 optical isolator is designed to provide a high-reliability, low power interface between logic devices, such as CPUs, microprocessors, and ASICs. In addition, the device can be used in applications where voltages higher than the logic or IC supply voltage need to be isolated from the equipment.

Function Principles

The HCPL-2611#020 logic output optoisolator is composed of two components-an emitting diode and detector, separated by a hermetically sealed plastic barrier. When voltage is applied to the emitting diode, it emits light, which is received by the detector. The detector converts the light into electrical energy and provides a logic output; this output is a voltage pulse, and can be used to switch digital logic functions. This process of converting light to electricity is what allows the HCPL-2611#020 to provide electrical isolation between two pieces of equipment.
