The ILD32/ILQ32 are 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 optocou-
plers can be used to replace reed and mercury
relays with advantages of long life, high speed
switching and elimination of magnetic fields.

The ILD32 has two isolated channels in a DIP pack-
age, and the ILQ32 has four channels. These
devices can be used to replace 4N32s or 4N33s in
applications calling for several single channel
optocouplers on a board.
