Additional Details:

The IL216A utilizes an infrared LED and a phototransistor to achieve electrical isolation. When current flows through the LED, it emits infrared light, which activates the phototransistor, allowing current to flow through the output circuit. The absence of a direct electrical connection between the input and output provides a high degree of isolation. The device is commonly available in a DIP package. It is designed to meet relevant safety standards for electrical isolation.
