DESCRIPTION

The 4N32 and 4N33 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 isola-
tion between driving and load circuits. These opto-
couplers can be used to replace reed and mercury
relays with advantages of long life, high speed
switching and elimination of magnetic fields.
