The PC817 is a low-input current, high-gain, phototransistor optocoupler integrated circuit. It serves as an optical coupler that consists of an infrared LED and a phototransistor encapsulated
The PC817 is a popular optocoupler, also known as an optoisolator, used to transfer electrical signals between two isolated circuits by means of light. Below is an overview of the PC817 optocoupler
