The SDN139 consists of a phototransistor photocoupled to a light-emitting diode. The high isolation level of the input-output coupling LED and phototransistor between the light can maintain a low level of DC signal control capability at the same time. The SDN139 provides opto-isolated methods for controlling multiple interface circuits for applications such as telecommunications, industrial control and instrumentation.
