This document introduces the features of HCPL0700, HCPL0701, HCPL0730, HCPL0731 products, including low input current, high gain split darlington optocouplers, single channel, dual channel, application scenarios, etc.
This document is a technical datasheet for the Fairchild Semiconductor HCPL0700, HCPL0701, HCPL0730, and HCPL0731 family of Low Input Current High Gain Split Darlington Optocouplers. The devices consist of an AlGaAs LED optically coupled to a high gain split darlington photodetector housed in a compact 8-pin small outline package.
| Low Input Current | 0.5mA |
|---|---|
| Superior CTR | 2000% |
