DESCRIPTION

The IL30/31/55, ILD30/31/55, and ILQ30/31/55 are

optically coupled isolators wih Gallium Arsenide

infrared emitters and silicon photodarlington sen-

sors. 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 applica-

tions.
