Optocoupler, 4N46-000E, BROADCOM

The 4N46-000E contains 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 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.
