DESCRIPTION
The IL66B is an optically coupled isolator  employing a Gallium Arsenide infrared emitter  and a silicon photodarlington detector. Switching  can be accomplished while maintaining a high  degree of isolation between driving and load circuits. They can be used to replace reed and mercury relays with advantages of long life, high  speed switching and elimination of magnetic  fields.
