The 4N45/46 optocouplers
contain a GaAsP light emitting
diode optically coupled to a high
gain photodetector IC.

• Digital Logic Ground
Isolation
• Low Input Current Line
Receiver
• Line Voltage Status
Indicator–Low Input Power
Dissipation
• Logic to Reed Relay Interface
• Level Shifting
• Interface Between Logic
Families
The excellent performance over
temperature results from the
inclusion of an integrated emitterbase 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. Compatibility 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.

*The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output
continuous voltage rating. For the continuous voltage rating refer to the VDE 0884 Insulation Characteristics Table (if applicable),
your equipment level safety specification, or Agilent Application Note 1074, “Optocoupler Input-Output Endurance Voltage.”
Notes:
1. Derate linearly above 50°C free-air
temperature at a rate of 0.4 mA/°C.
2. Derate linearly above 50°C free-air
temperature at a rate of 0.7 mW/°C.
3. Derate linearly above 25°C free-air
temperature at a rate of 0.8 mA/°C.
4. Derate linearly above 25°C free-air
temperature at a rate of 1.5 mW/°C.
5. DC CURRENT TRANSFER RATIO is
defined as the ratio of output
collector current, I O, to the forward
LED input current, I F, times 100%.

Current vs. Forward Voltage.
7. Device considered a two-terminal
device: Pins 1, 2, 3 shorted together
and Pins 4, 5, and 6 shorted together.
8. Use of a resistor between pin 4 and 6
will decrease gain and delay time.
(See Figures 11, 12, and 13.)
9. Common mode transient immunity in
Logic High level is the maximum
tolerable (positive) dVcm /dt on the
leading edge of the common mode
pulse, VCM , to assure that the output
will remain in a Logic High state (i.e.,
VO > 2.5 V). Common mode transient
immunity in Logic Low level is the
maximum tolerable (negative)
dVcm/dt on the trailing edge of the
common mode pulse signal, Vcm , to
assure that the output will remain in
a Logic Low state (i.e., VO < 2.5 V).
10. In accordance with UL 1577, each
optocoupler is proof tested by
applying an insulation test voltage
≥ 3000 V rms for 1 second (leakage
detection current limit, I I-O ≤ 5 µA).
