The 150 Mbps data rate covers most industrial fieldbus and sensor interfaces without timing margin concerns.
The 10000 Vrms isolation rating is the standout spec — it provides reinforced insulation for systems that must survive high-voltage transients, such as traction inverters or grid-tied chargers. The 150 Mbps data rate, with 10 ns propagation delay and 3 ns pulse-width distortion, keeps bus timing tight for high-speed SPI or CAN FD links. The supply range of 2.25 V to 5.5 V on both sides lets you run the isolator from a 3.3 V MCU on one side and a 5 V transceiver on the other without a level shifter. The 3/1 channel direction (three channels from side 1 to side 2, one reverse) is set for common SPI configurations: MOSI, SCLK, and CS forward, MISO back.
