Typical Performance Curves and Interpretation

The separates high-voltage input lines from low-voltage outputs using an internal short optical path. An AlGaAs infrared light-emitting diode (LED) converts electrical inputs to optical signals, which cross an internal insulating layer to strike an integrated, high-gain photodetector gate.

What or switching frequency does your design require?

The first page gives a summary of the device, including its basic description (optocoupler, containing a GaAsP LED and high-gain photo detector), key features, a simplified schematic, and typical applications.

Note: A 0.1 µF bypass capacitor must be connected between pins 5 and 8 to ensure stable operation. 3. Common Applications

Digital logic transitions power an internal infrared LED. This emitted light crosses a physically isolated air gap or glass barrier inside the chip, completely preventing raw current from crossing between the input and output networks.
