描述 Description

These dual channel optocouplers contain a separated pair of GaAsP light emitting diodes optically coupled to a pair of integrated high gain photo detectors. They provide extremely high current transfer ratio and excellent inputoutput common mode transient immunity. A separate pin for the photodiodes and first gain stages (VCC) permits lower output saturation voltage and higher speed operation than possible with conventional photodarlington type optocouplers. In addition, VCC may be as low as 1.6 V
