SDT1600
DC Input
Quad Optocoupler
The SDT1600 combines four independent optocouplers in a 16 pin DIP/SMD package. Each of the four optocoupler circuits is composed
of an input LED optically-coupled to a Phototransistor--allowing for high isolation levels while maintaining low-level DC signal control
capability. The SDT1600 provides an optically isolated method of controlling many interface applications such as telecommunications,
industrial control and instrumentation circuitry.
