Description

The IL5xB and MOC8021 are optically coupled isola-

tors 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 optocouplers can be

used to replace reed and mercury relays with advan-

tages of long life, high speed switching and elimina-

tion of magnetic fields.

Absolute Maximum Ratings

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.
