DESCRIPTION

typ.
The IL55B is an optically coupled isolator with a Gal-
lium Arsenide infrared LED and a silicon photodarling-
ton 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 advantages of
long life, high speed switching and elimination of
magnetic fields.
