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
feedback.

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.
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
voltage of the output transistor
and by the guaranteed maximum
output leakage (IOH) at 18 V.
The 4N45 has a 250% minimum
CTR at 1.0 mA input current and
a 7 V minimum breakdown
voltage rating.
Selection for lower input current
down to 250 µA is available upon
request.
