Optocoupler
Layout symbol
LED and phototransistor in one package, so a signal can pass between two circuits that are electrically separated. Drive the LED side through a resistor like a normal LED; the transistor side then works as a switch, often with a pull-up resistor. Used to isolate a microcontroller from mains or noisy circuits.
