High Gain Darlington Output

Optocouplers

Technical Data

4N45

4N46

The high current transfer ratio at

very low input currents permits

circuit designs in which adequate

margin can be allowed for the

effects of optical coupling

variations.

Features

• High Current Transfer

Ratio–1500% Typical

• Low Input Current

Requirement–0.5 mA

• Performance Guaranteed

over 0°C to 70°C

Description

The 4N45/46 optocouplers

contain a GaAsP light emitting

diode optically coupled to a high

gain photodetector IC.

The excellent performance over

temperature results from the

inclusion of an integrated emitter-

base bypass resistor which shunts

photodiode and first stage

leakage currents as well as

bleeding off excess base drive to

ground. External access to the

second stage base provides the

capability for better noise

rejection than a conventional

photodarlington detector. An

external resistor or capacitor at

the base can be added to make a

gain-bandwidth or input current

threshold adjustment. The base

lead can also be used for

The 4N46 has a 350% minimum

CTR at an input current of only

0.5 mA making it ideal for use in

low input current applications

such as MOS, CMOS and low

power logic interfacing. Compat-

ibility with high voltage CMOS

logic systems is assured by the

20 V minimum breakdown
