SSOUSA SDT800

SDT800
DC Input Dual
Optocoupler
DESCRIPTION
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.
