SDD450

SDD450 DC Input Photo-Darlington Optocoupler DESCRIPTION The SDD450 consists of a Photo Darlington transistor optically coupled to a light emitting diode. Optical coupling between the input LED and output Photo Darlington allows for high isolation levels while maintaining low-level DC signal control capability. The SDD450 provides an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry.
