The Maxim Integrated MAX14931EASE+ is a 4-channel general-purpose digital isolator using capacitive coupling to pass signals across a 2750 Vrms isolation barrier. Three channels run from side 1 to side 2, one channel runs the opposite direction.
The MAX14931EASE+ supports a maximum data rate of 25 Mbps.
Yes, the supply voltage range goes down to 1.71 V, so the isolator can operate on a 1.8 V logic rail directly.
Yes. With three channels in one direction and one in the other, the 3/1 channel split matches the typical SPI interface (SCK, MOSI, CS out, MISO in). The 25 Mbps data rate supports SPI clock speeds up to 12.5 MHz with margin.
