DESCRIPTION

The 66015 contains a gallium arsenide infrared LED optically coupled to a silicon planar phototransistor. The optocoupler is

built in a TO-46 Package. The collector of the phototransistor is electrically connected to the case. This optocoupler is

capable of transmitting signals between two galvanic sources. The potential difference between transmitter and receiver

should not go over the maximum isolation voltage. The internal base connection has been eliminated for improved noise

immunity.
