Operating from a 4.5V to 5.5V supply, it fits into 5 V logic systems directly. ## 75 ns propagation delay and 5 kV/µs common-mode immunity Propagation delay is 75 ns max in both directions (tpLH and tpHL), which at 10 Mbps leaves roughly 25 ns of the bit period for jitter and skew budget. The minimum common-mode transient immunity of 5 kV/µs means the part rejects fast voltage transients between grounds — relevant in motor-drive or inverter applications where the switching node slews at several kV/µs. Rise time is 17 ns typical, fall time 5 ns typical; the asymmetry creates a duty-cycle skew of about 12 ns, which a downstream Schmitt trigger or FPGA input can absorb at 10 Mbps. ## Active production, ROHS3, 8-SOIC package The 8-SOIC (0.154-inch body width, 3.90 mm) package is a common footprint shared with many single- and dual-channel optoisolators, making it a drop-in candidate for existing layouts.","metaTitle":"HCPL0637R2 onsemi Optoisolator 10 Mbps 3750 Vrms 8-SOIC","metaDescription":"onsemi HCPL0637R2 dual-channel optoisolator, 10 Mbps data rate, 3750 Vrms isolation, open-collector Schottky-clamped output, 8-SOIC package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"10Mbps","Input Type":"DC","Output Type":"Open Collector, Schottky Clamped","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Channels":"2","Base Product Number":"HCPL0637","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C~85°C","Inputs - Side 1/Side 2":"2/0","Rise / Fall Time (Typ)":"17ns, 5ns","Supplier Device Package":"8-SOIC","Current - Output / Channel":"15 mA","Voltage - Forward (Vf) (Typ)":"1.75V (Max)","Current - DC Forward (If) (Max)":"-","Propagation Delay tpLH / tpHL (Max)":"75ns, 75ns","Common Mode Transient Immunity (Min)":"5kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.7200","priceTiers":[{"qty":1,"price":"$3.72000","currency":"USD"},{"qty":10,"price":"$2.63100","currency":"USD"},{"qty":100,"price":"$2.15520","currency":"USD"},{"qty":500,"price":"$1.81686","currency":"USD"},{"qty":1000,"price":"$1.66650","currency":"USD"},{"qty":2500,"price":"$1.59758","currency":"USD"},{"qty":5000,"price":"$1.56626","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d87989943ba65496217d84f8b6494a2d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/HCPL0637R2/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of HCPL0637R2?","answer":"The HCPL0637R2 is rated for 10 Mbps data rate."},{"question":"Does HCPL0637R2 replace HCPL0637?","answer":"The base product number is HCPL0637; the HCPL0637R2 suffix indicates Tape & Reel packaging.
