The 6N139 is an optically coupled high speed integrated circuit (IC) with a built-in isolator. It is a dual-channel, 8-pin dual in-line package (DIP) device. It is designed to provide electrical isolation between two circuits while allowing them to communicate with each other.The 6N139 is a high speed optocoupler with a maximum data transfer rate of 10 Mbps. It features a low input current of 1 mA, a low output current of 10 mA, and a high common mode transient immunity of 15 kV/μs. The device is also designed to provide a high level of noise immunity and a wide operating temperature range of -40°C to {+}85°C.The 6N139 is commonly used in industrial automation, motor control, and power electronics applications. It can be used to provide electrical isolation between two circuits, allowing them to communicate with each other without the risk of electrical shock or interference. It is also used in medical equipment, telecommunications, and other applications where electrical isolation is required.(For reference only)
