4N45 Datasheet (HP) - High Gain Darlington Output Optocouplers

4N45, High Gain Darlington Output Optocouplers

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 blee
