4N45/4N46 High Gain Darlington Output Optocouplers Data Sheet Description Features The 4N45/46 optocouplers contain a GaAsP light High current transfer ratio 1500% typical emitting diode optically coupled to a high gain Low input current requirement 0.5 mA photodetector IC. Performance guaranteed over 0C to 70C temperature range The excellent performance over temperature results Internal base-emitter resistor minimizes output from the inclusion of an integrated emitter-base leakage bypass resistor which shunts photodiode and first Gain-bandwidth adjustment pin stage leakage currents as well as bleeding off excess Safety approval base drive to ground. External access to the second UL Recognized -3750 V rms for 1 minute stage base provides the capability for better noise CSA Approved IEC/EN/DIN EN 60747-5-2 rejection than a conventional photodarlington detector. An external resistor or capacitor at the base can be added to make a gain-bandwidth or input Applications current threshold adjustment. The base lead can also Telephone ring detector be used for feedback. Digital logic ground isolation Low input current line receiver The high current transfer ratio at very low input Line voltage status indicatorlow input power currents permits circuit designs in which adequate dissipation margin can be allowed for the effects of optical Logic to read relay interface coupling variations. Level shifting The 4N46 has a 350% minimum CTR at an input Interface between logic families current of only 0.5 mA making it ideal for use in low input current applications such as MOS, CMOS and Functional Diagram low power logic interfacing. Compatibility with high voltage CMOS logic systems is assured by the 20 V TRUTH TABLE (POSITIVE LOGIC) minimum breakdown voltage of the output transistor 6 ANODE 1 V B LED OUTPUT and by the guaranteed maximum output leakage ON L (I ) at 18 V. OH 5 OFF H CATHODE 2 V O The 4N45 has a 250% minimum CTR at 1.0 mA input current and a 7 V minimum breakdown voltage * JEDEC Registered Data 4 3 GND ** JEDEC Registered up to rating. 70C. Selection for lower input current down to 250 A is available upon request. CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD.Ordering Information 4N45/4N46 are UL Recognized with 3750 Vrms for 1 minute per UL1577 and is approved under CSA Component Acceptance Notice 5, File CA 88324.
