The SDT400 consists of a phototransistor optically coupled to a light emitting diode. Optical coupling between the input LED and output
phototransistor allows for high isolation levels while maintaining low-level DC signal control capability. The SDT400 provides an optically
isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry.
