4N35 Optocoupler/Phototransistor IC - DIP-6 Package [C] Transistors 3V and 5V microcontrollers boardsPhototransistors means they are transistors which are controlled by a beam of light provided by an IR LED so construction wise this IC has an IR LED which when powered make the transistor in the IC conduct. This IC can be used as a fast and isolating substitute for the Electromechanical Relays which comes very handy when you are trying to isolate a noisy signal from your digital IC design. You can also use this IC as a logical isolated Buffer with
