The SI8261BCA-C-IS is an optocoupler integrated circuit manufactured by Silicon Labs for general purpose applications. It is designed to help isolate electrical signals between two circuits, and it employs an optically coupled array of LEDs and photodiodes to perform this task. The device is 6-pin and has a logic gate drive current output, a logic gate turn-on voltage input, and a voltage-controlled bipolar output. It can be used to isolate digital or analog signals, and it is AEC-Q100 qualified, making it ideal for automotive applications.
