DESCRIPTION

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

optically coupled isolators with 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 applications.
