HCPL-0731
Overview
These dual-channel optocouplers contain a separated pair of Ga As P light-emitting diodes optically coupled to a pair of integrated high-gain photodetectors. They provide extremely high current transfer ratio and excellent input-output mon mode transient immunity. A separate pin for the photodiodes and first gain stages (VCC) permits lower output saturation voltage and higher speed operation than possible with conventional photo-darlington type optocouplers. In addition, VCC may be as low as 1.6V without adversely affecting the parametric performance.
These dual-channel optocouplers are available in an 8-pin DIP and in an industry standard SO-8 package. The following is a cross reference table listing the 8-pin DIP part number and the electrically equivalent SOIC-8 part number.

The SO-8 does not require “through holes” in a PCB. This package occupies approxmately one-third the footprint area of the standard dual-inline...
