Special purpose isolators use one- and two-channel optoelectronic circuits to perform specific tasks such as I2C repeaters, line receivers, current loop receivers and transmitters, optical power converters, photocell optocouplers, power MOSFETs, and power transistor drivers. Mounting types include surface, through-hole and free-hanging. Voltage supply and output current are among the key differentiation parameters.
