SDT400

SDT400 DC Input Optocoupler DESCRIPTION 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.
