DESCRIPTION
The ILQ32 is optically coupled isolators 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 advantages of long life, high speed
switching and elimination of magnetic fields.
