The ISO6742FDWR: The device offers four unidirectional channels arranged as two inputs on side 1 and two inputs on side 2, matching the typical split of a half-duplex SPI bus (SCLK, MOSI on one side; MISO, CS on the other) or a CAN transceiver interface. Rise and fall times are matched at 2.6 ns typical, and the maximum pulse-width distortion is 7 ns — tight enough that the isolator does not eat into the bit-time budget at 50 Mbps.
Yes. With a 50 Mbps data rate, 2/2 channel split, and 18 ns propagation delay, the ISO6742FDWR directly supports SPI bus isolation at standard clock rates. The unidirectional channels map naturally to SCLK, MOSI, MISO, and chip-select lines.
