DESCRIPTION
.130 (3.30)
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.
