Description

The HCPL0700, HCPL0701, HCPL0730 and HCPL0731
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 HCPL0730
and HCPL0731 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 0.5mA
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.

A

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

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
leading edge of the common mode pulse signal, V
(i.e., V

> 2.0V). Common mode transient immunity in logic low level is the maximum tolerable (negative) dV
