DESCRIPTION

The MOC8050 is an optically coupled isolator with a
Gallium Arsenide infrared emitter and a silicon pho­todarlington sensor. Switching can be achieved
while maintaining a high degree of isolation
between driving and load circuits, with no cross talk
between channels. These optocouplers can be
used to replace reed and mercury relays with
advantages of long life, high speed switching and
elimination of magnetic fields.
