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

tion voltage and higher speed

operation than possible with

conventional photodarlington

type optocouplers. In addition,

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.

*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.
