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.

FEATURES

• Very high current transfer ratio, 500 min.

• High isolation resistance, 1011 Ω typical

• Standard plastic DIP package

• Material categorization:
