The device accepts low voltage TTL/CMOS logic signals and converts them to a differential current output of typically 3.1 mA for driving a transmission medium such as a twisted- pair cable. The transmitted signal develops a differential voltage of typically 355 mV across a termination resistor at the receiv- ing end, and this is converted back to a TTL/CMOS logic level by a line receiver.
