4N46

High Gain Darlington Output Optocouplers Technical Data 4N45 4N46 Features High Current Transfer Ratio–1500% Typical Low Input Current Requirement–0.5 mA Performance Guaranteed over 0°C to 70°C Temperature Range Internal Base-Emitter Resistor Minimizes Output Leakage Gain-Bandwidth Adjustment Pin Safety Approval UL Recognized -2500 V rms for 1 Minute CSA Approved Applications Telephone Ring Detector 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 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 emitterbase bypass resistor which shunts photodiode and first stage leakage currents as well as bleeding off excess base d...
