It sits between two supply domains — 2.5V to 5.5V on each side — so a 3.3V MCU can talk to a 5V peripheral without ground loops or level-shifting the data lines. Rated for 150 Mbps per channel, the propagation delay is 13 ns max with 4 ns typical rise/fall times. That timing budget leaves headroom for SPI clock rates up to 50 MHz or parallel bus interfaces where the total skew across six lines must stay under 4.5 ns pulse-width distortion. ## Channel count and direction — 3/3 split Six unidirectional channels are split 3 inputs on side 1 and 3 inputs on side 2. That fixed direction means the part fits designs where the data flow is known at layout time — three lines from the controller to the peripheral, three back. For bidirectional buses like I²C or RS-485 half-duplex, a different channel configuration or external direction control is needed. Common-mode transient immunity is 50 kV/µs minimum. In a motor-drive or inverter environment where the ground plane jumps several hundred volts in a few nanoseconds, that rating keeps the output from glitching — the isolator rejects the dV/dt rather than passing it through as a data error. ## Package and temperature grade Surface-mount assembly with a standard reflow profile; no special bake required if the moisture sensitivity level is observed per the label. The 2500Vrms isolation is a basic-reinforced rating for equipment-level isolation, not patient-contact medical — suitable for PLC I/O modules, motor drives, and isolated sensor interfaces.","metaTitle":"Skyworks SI8663EB-B-IU Digital Isolator, 6Ch, 150Mbps","metaDescription":"Skyworks SI8663EB-B-IU general-purpose digital isolator: 6 unidirectional channels, 150Mbps data rate, 2500Vrms isolation, 50kV/µs CMTI, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Package":"Tube","Data Rate":"150Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.5V ~ 5.5V","Number of Channels":"6","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"3/3","Rise / Fall Time (Typ)":"4ns, 4ns","Supplier Device Package":"16-QSOP","Pulse Width Distortion (Max)":"4.5ns","Propagation Delay tpLH / tpHL (Max)":"13ns, 13ns","Common Mode Transient Immunity (Min)":"50kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.33","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.33000","currency":"USD"},{"qty":10,"price":"$4.78400","currency":"USD"},{"qty":25,"price":"$4.52240","currency":"USD"},{"qty":100,"price":"$3.91930","currency":"USD"},{"qty":250,"price":"$3.71832","currency":"USD"},{"qty":500,"price":"$3.33644","currency":"USD"},{"qty":1000,"price":"$2.81386","currency":"USD"},{"qty":2500,"price":"$2.67317","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d0fd34ad18bd716c3bfaa7fe80e62960.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional alternative to SI8663EB-B-IU?","answer":"The SI8663BB-B-IU is the closest peer — same 6-channel count, same 3/3 input split, same 150 Mbps data rate, same 2500Vrms isolation, and same 16-SSOP package.
