The 0.8 ns typical rise and 1 ns fall times keep edge rates clean for high-speed serial links. If your design runs a 50 MHz SPI bus or a 10 Mbps CAN FD node, the timing headroom is comfortable. ## 3000Vrms and 50 kV/µs CMTI — isolation for motor drives and inverters The 3000Vrms isolation rating meets basic safety isolation requirements for industrial equipment. The 50 kV/µs common-mode transient immunity (typical) is the spec that matters when this isolator sits between a controller and a gate-driver in a motor-drive or inverter: fast-switching SiC or GaN stages generate high dV/dt on the isolated side, and the MAX22291CASA/V+ won't latch or corrupt data.","metaTitle":"MAX22291CASA/V+ Digital Isolator, 200 Mbps, 3000Vrms, 8-SOIC","metaDescription":"MAX22291CASA/V+ 2-channel digital isolator with capacitive coupling, 200 Mbps data rate, 3000Vrms isolation, 1.71V-5.5V supply.
