HCPL-2631#500: Optoisolators - Logic Output Application Field and Working Principle

Optoisolators are electrical components used primarily for reducing electrical noise, isolating circuits, and reducing the amount of current allowed to flow between two connected circuits. The HCPL-2631#500 optoisolator is a specific type of optoisolator that falls under the category of Logic Output-Optoisolators. The Logic Output-Optoisolator uses a special type of light source as a way to output electrical signals. The most common type of light source used for Logic Output-Optoisolators is an LED, or light emitting diode. This type of device is used because it has a very small current draw and can be actively switched on and off with small pulses of current. The HCPL-2631#500 specifically uses a 600mA high-speed output LED that is mounted on the package’s centerline. This LED is split between two outputs and when a signal is sent across the controlled gate it is split into a low and a high output. The LED is turned on or off depending on the state of the logic signal the Logic Output-Optoisolator is receiving. When the logic signal is high, the LED will be turned on, and when the logic signal is low the LED will be off. When the LED is off, no current flows through the LED and hence no current will be flowing between the two connected circuits. The HCPL-2631#500 has a maximum current transfer of up to 40mA and a maximum capacitance of 10pF. The temperature range under which the HCPL-2631#500 operates ranges from -55-125°C. It is also RoHS and UL approved.The HCPL-2631#500 optoisolator is typically used in data transmission and communication equipment such as modems, ISDN, communications controllers, personal computers, telecommunications, and process control systems. The HCPL-2631#500 is also used in automotive applications such as instrument clusters, door and window controllers, and engine controllers. The HCPL-2631#500 is a preferred optoisolator because of its low voltage drop, low power consumption, and high speed performance. In conclusion, the HCPL-2631#500 is a Logic Output-Optoisolator that is used for isolating circuits and reducing electrical noise. It uses a 600mA high-speed output LED that is mounted on the package’s centerline and is capacited with a maximum current transfer of up to 40mA. The HCPL-2631#500 is typically used in data transmission and communication equipment such as modems, ISDN, personal computers, telecommunications, and process control systems.
