LOW INPUT CURRENT
HIGH GAIN SPLIT
DARLINGTON OPTOCOUPLERS
DESCRIPTION
The HCPL-0700 and HCPL-0701 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 split darlington configuration separating the input photodiode
and the first stage gain from the output transistor permits lower out-
put 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.
