Technical content
The SDT800 consists of two phototransistors, each optically coupled to a light emitting diodes for DC input operation. Optical coupling between the input LEDs and output phototransistor allows for high isolation levels while maintaining low-level DC signal control capability. The SDT800 provides an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry.
