Description
These dual channel optocouplers
contain a separated pair of GaAsP
light emitting diodes optically
coupled to a pair of integrated
high gain photo detectors. They
provide extremely high current
transfer ratio and excellent input-
output common mode transient
immunity. A separate pin for the
photodiodes and first gain stages
(VCC) permits lower output satura-
tion voltage and higher speed
operation than possible with
conventional photodarlington
type optocouplers. In addition,
VCC may be as low as 1.6 V

*5000 V rms/1 minute withstand voltage rating is for Option 020 (HCPL-2730, HCLP-2731) products only.
A 0.1 µF bypass capacitor connected between pins 5 and 8 is recommended.
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to
prevent damage and/or degradation which may be induced by ESD.
