DESCRIPTION
The HCPL-0700, HCPL-0701, HCPL-0730 and HCPL-0731 optocouplers consist of an AlGaAs LED optically coupled to a high
gain split darlington photodetector housed in a compact 8-pin small outline package. The HCPL-0730 and HCPL-0731 devices
have two channels per package for optimum mounting density.
The split darlington configuration separating the input photodiode and the first stage gain from the output transistor permits lower
output saturation voltage and higher speed operation than possible with conventional darlington phototransistor optocoupler.
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, CMOS, LSTTL and EIA RS232C, while output compatibility is ensured to CMOS as well as high
fan-out TTL requirements.

NOTES
1. Current Transfer Ratio is defined as a ratio of output collector current, I
O
, to the forward LED input current, I
F
, times 100%.
2. Pin 7 open. Use of a resistor between pins 5 and 7 will decrease gain and delay time.
3. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV
CM
/dt on the leading edge of the
common mode pulse signal, V
CM
, to assure that the output will remain in a logic high state (i.e., V
O
>2.0 V). Common mode
transient immunity in logic low level is the maximum tolerable (negative) dV
CM
/dt on the trailing edge of the common mode
pulse signal, V
CM
, to assure that the output will remain in a logic low state (i.e., V
O
<0.8 V).
4. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are shorted together.
5. 2500 VAC RMS for 1 minute duration is equivalent to 3000 VAC RMS for 1 second duration.
