OLH5730 / OLH5731

Hermetic Low Input Current, Dual-Channel Optocouplers

The OLH5730/5731 are dual-channel, hermetic 8-pin dual in-line package (DIP) optocouplers for low input current applications. The OLH5731 product is a 100 percent high-reliability screened version of the OLH5730.

Each channel consists of an Aluminum Gallium Arsenide (AlGaAs) LED optically coupled to an integrated photodiode, split Darlington detector. The AlGaAs LED provides superior low current performance. The split Darlington open collector output results in high gain and low saturation voltage.

The OLH5730/5731 products are functionally compatible to the HCPL2730/2731 and 6N140A optocouplers. The performance of the OLH5730/5731 products under a radiation environment is significantly improved over standard phototransistors.

Special low input current or current transfer ratio (CTR) selection are available upon request.
