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.
