The OLH5600/5601 are hermetic 8-pin dual in-line package (DIP) optocouplers for high-speed digital applications. The OLH5601 product is a 100 percent high-reliability screened version of the OLH5600. Each unit consists of an Aluminum Gallium Arsenide (AlGaAs) LED optically coupled to an integrated photodetector that provides 3000 VDC electrical isolation between the input and output. An internal shield provides excellent common mode rejection (CMR) performance. The OLH5600/5601 products are functionally compatible to 6N134, 6N137, HCPL2601, and HCPL5600/5601 optocouplers. Special CMR selection and lower threshold current are available upon request.
