4N33 Optocoupler, Photodarlington Output, High Gain, With Base Connection

class='font-size-24

mb-3'>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.
