מבדדים אופטיים - יציאת לוגיקה

Logic output optoisolators use light to transmit information across an electrical insulation barrier, usually for safety or functional reasons. They are distinguished from other styles of optoisolator products by the incorporation of additional output stage circuitry for amplification and threshold detection, providing output signals that are compatible with common logic signal levels. These additional circuits require provision of an external power source for proper operation.
