H11A1 optocoupler equivalent, optocoupler.
* Interfaces with common logic families
* Input-output coupling capacitance < 0.5 pF
* Industry standard dual-in line 6-pin package
* Isolation rated volt.
* AC mains detection
* Reed relay driving
* Switch mode power supply feedback
* Telephone ring detection.
The H11A1 is an industry standard single channel phototransistor coupler.
Each optocoupler consists of gallium arsenide infrared LED and a silicon NPN phototransistor.
The isolation performance is accomplished through Vishay double molding isolation .
