4N45/4N46  
HighGainDarlingtonOutputOptocouplers  
DataSheet  
Description  
Features  
The 4N45/46 optocouplers contain a GaAsP light  
emitting diode optically coupled to a high gain  
photodetector IC.  
• High current transfer ratio – 1500% typical  
• Low input current requirement – 0.5 mA  
• Performance guaranteed over 0°C to 70°C temperature  
range  
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  
• Internal base-emitter resistor minimizes output  
leakage  
• Gain-bandwidth adjustment pin  
• Safety approval  
UL Recognized -3750 V rms for 1 minute  
CSA Approved IEC/ EN/ DIN EN 60747-5-2  
base can be added to make a gain-bandwidth or input Applications  
current threshold adjustment. The base lead can also  
be used for feedback.  
• Telephone ring detector  
• Digital logic ground isolation  
• Low input current line receiver  
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.  
• Line voltage status indicator–low input power  
dissipation  
• Logic to read relay interface  
• Level shifting  
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  
minimumbreakdownvoltageoftheoutputtransistor  
and by the guaranteed maximum output leakage  
(IOH) at 18 V.  
• Interface between logic families
