S
AT800
AC Input Dual
Optocoupler
The S
AT800 consists of two phototransistors, each optically coupled to two input LEDs. for AC input operation. Optical coupling
between the input LEDs and output phototransistor allows for high isolation levels while maintaining low-level
AC signal control capability.
The S
AT800 provides an optically isolated method of controlling many interface applications such as telecommunications, industrial control
and instrumentation circuitry.
