With a 4/1 input split (four channels on side 1, one on side 2), it handles a typical SPI bus plus an extra control line — chip select plus three data lines on one side, a single interrupt or enable on the other. Rated for 150 Mbps, the propagation delay sits at 13 ns max with 4.5 ns pulse-width distortion — tight enough for most isolated SPI or UART links without needing a separate clock recovery. The 35 kV/µs common-mode transient immunity means it holds data integrity when switching motor drives or relays on the same board. ## Supply flexibility and temperature range Operating from -40°C to 125°C, it fits industrial enclosures, motor drives, and outdoor telecom gear where ambient temps climb. Packaged in the 16-SOIC wide-body (0.295-inch width, 7.50 mm), the footprint matches the standard high-isolation SOIC-16 land pattern. The part is RoHS3 compliant.","metaTitle":"Skyworks SI8651ED-B-IS Digital Isolator, 5Ch, 150Mbps","metaDescription":"Skyworks SI8651ED-B-IS digital isolator: 5 unidirectional channels, 150 Mbps, 5000 Vrms isolation, -40 to 125°C.
