At 150Mbps, this isolator handles high-speed SPI, serial ADC/DAC links, and isolated UART lines without bit-rate bottlenecks — the 13ns max propagation delay and 2.5ns typical rise/fall time keep timing margins intact across the barrier. ## Channel direction and supply flexibility With 3 inputs on side 1 and 1 input on side 2, the channel configuration suits applications where the majority of data flows from one domain to the other — for example, an isolated SPI bus with three signals (SCLK, MOSI, CS) crossing from the controller side and one (MISO) returning. ## Noise immunity and temperature grade Common-mode transient immunity of 35kV/µs minimum means the isolator holds its data state through fast voltage spikes between ground domains — a motor-drive inverter switching at 10-20 kHz generates dV/dt edges that can couple across a barrier; this part shrugs them off without bit errors.","metaTitle":"SI8641ED-B-ISR Skyworks Digital Isolator, 5000Vrms, 150Mbps","metaDescription":"Skyworks SI8641ED-B-ISR general-purpose digital isolator: 4 channels, 5000Vrms isolation, 150Mbps data rate, -40°C to 125°C.

Both share the same 150Mbps data rate, 3/1 channel configuration, 13ns propagation delay, and 35kV/µs common-mode transient immunity.
