DESCRIPTION

The IL30/31/55, ILD30/31/55, and ILQ30/31/55 are optically coupled isolators wih Gallium Arsenide infrared emitters and silicon photodarlington sensors. Switching can be achieved while maintaining a high degree of isolation between driving and load circuits, with no crosstalk 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.

The Il30/31/55 are equivalent to MCA230/MCA231/MCA255. The ILD30/31/55 re designed to reduce board space requirements in high density applications.
