Description
The 4N32 and 4N33 are optically coupled isolators
with a gallium arsenide infrared LED and a solicon
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 advantages of long life, high
speed switching and elimination of magnetic fields.

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.
