Description
The IL30/ IL31/ IL55 single, ILD30/ ILD31/ ILD55
dual, and ILQ30/ ILQ31/ ILQ55 quad are optically
coupled isolators with Gallium Arsenide infrared emit-
ters 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/ IL31/ IL55 are equivalent to MCA230/
MCA231/ MCA255. The ILD30/ ILD31/ ILD55 are
designed to reduce board space requirements in high
density applications.

Absolute Maximum Ratings
T
amb
= 25 C, unless otherwise specified
Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. Functional operation of the device is
not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
Maximum Rating for extended periods of the time can adversely affect reliability.
