Proton Tolerant Optocoupler

The 66228 contains a gallium arsenide infrared LED optically coupled to a silicon planar phototransistor. The optocoupler is built on a TO-46 header. The anode of the LED is electrically connected to the case. The internal base connection has been eliminated for improved noise immunity.
