	DESCRIPTION
	The 6N138/9 and HCPL-2730/HCPL-2731 optocouplers consist of an AlGaAs LED
	optically coupled to a high gain split darlington photodetector.
	The split darlington configuration separating the input photodiode and the first	8
	stage gain from the output transistor permits lower output saturation voltage and	1
	higher speed operation than possible with conventional darlington phototransistor
	optocoupler. In the dual channel devices, HCPL-2730/HCPL2731, an integrated
	emitter - base resistor provides superior stability over temperature.
	The combination of a very low input current of 0.5 mA and a high current transfer
	ratio of 2000% makes this family particularly useful for input interface to MOS,	8
	CMOS, LSTTL and EIA RS232C, while output compatibility is ensured to CMOS as
		8
	well as high fan-out TTL requirements.
