Current Loop Driver.

Low Input Current Line Receiver.

CMOS Logic Interface.

The TOSHIBA 6N138 and 6N139 consists of a GaA?As

infrared emitting diode coupled with a split-Darlington output configuration.

A high speed GaA?As Ired manufactured with an unique LPE junction, has the virtue of fast rise and fall time at low drive current.
