4N45 optocouplers equivalent, high gain darlington output optocouplers.
* High Current Transfer Ratio
–1500% Typical
* Low Input Current Requirement
–0.5 mA
* Performance Guaranteed over 0°C to 70°C T.
* Telephone Ring Detector
* Digital Logic Ground
Isolation
* Low Input Current Line Receiver
* Line Volt.
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 photodiod.
