SDT4

70

DC Input

Optocoupler

The SDT4

70 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 SDT4

70 provides an optically

isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry.
