DESCRIPTION
The H11DX and 4N38 are phototransistor-type optically coupled optoisolators. An infrared emitting
diode manufactured from specially grown gallium arsenide is selectively coupled with a high voltage
NPN silicon phototransistor. The device is supplied in a standard plastic six-pin dual-in-line package.
