Photo Coupler – Photo Transistor 8Pin SOP-DC


Photo Transistor 8Pin SOP-DC

The EL20X and EL21X series contain an infrared emitting diode optically coupled to a phototransistor detector. The ELD20X and ELD21X series contain two infrared emitting diodes optically coupled to two phototransistor detectors. The devices are packaged in an 8-pin small outline package which conforms to the standard SO-8 footprin
