DESCRIPTION
The IL5xB and MOC8021 are optically coupled isola-
tors with a Gallium Arsenide infrared LED and a silicon
photodarlington sensor. Switching can be achieved
while maintaining a high degree of isolation between
driving and load circuits. These optocouplers can be
used to replace reed and mercury relays with advan-
tages of long life, high speed switching and elimina-
tion of magnetic fields.
