SDD451
DC Input
Optocoupler
DESCRIPTION
The SDD451 consists of a photo Darlington transistor 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 SDD451 provides an
optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation
circuitry.
