HCPL-7611-000E – AVAGO

The HCPL-7611-000E, manufactured by AVAGO, is an optoisolator designed for applications requiring high-voltage isolation. This device integrates an LED and a photodetector within an 8-pin DIP package. It provides a minimum isolation voltage of 3.75 kV. The output stage is configured as an open-collector transistor, allowing for flexible interfacing with various logic families and enabling wired-OR configurations. The open-collector output facilitates pull-up resistor selection to optimize switching speed and output voltage levels. This optoisolator is commonly used in applications such as industrial control systems, motor drives, and power supplies where electrical isolation is crucial for safety and signal integrity. The device’s construction ensures effective galvanic isolation between the input and output circuits, preventing ground loops and protecting sensitive circuitry from voltage transients.
