Four-channel digital isolator for industrial signal isolation
Three channels run from side 1 to side 2, one channel runs the opposite direction — a 3/1 split that suits typical applications like isolating a microcontroller's UART or SPI lines where the bulk of data flows one way. The 1Mbps data rate handles slower serial buses comfortably; don't plan on pushing it past that for high-speed interfaces.
3750Vrms isolation and industrial temperature range
Rated for 3750Vrms isolation, this part meets the basic insulation requirements for many industrial, medical, and motor-drive applications where you need to break ground loops or protect low-voltage logic from high-side transients. Common-mode transient immunity of 25kV/µs minimum means it won't glitch when a motor drive or relay kicks.
Supply flexibility and timing margins
The supply range is split: side 1 runs from 1.8V to 5.5V, side 2 from 3V to 5.5V. That 1.8V capability on the input side is handy when isolating a low-voltage FPGA or MCU bank. Propagation delay is 90ns max each way, with 6ns pulse-width distortion — tight enough for 1Mbps signalling without bit-width errors. Rise/fall times of 2.5ns typical keep edge rates clean for short PCB traces.
