Dual-channel digital isolator for industrial signal isolation
It supports a data rate of 25 Mbps with propagation delays of 42 ns max and pulse-width distortion of 2 ns max, making it suitable for isolating high-speed digital signals such as SPI, UART, or CAN in noisy industrial environments.
25 Mbps data rate and 42 ns propagation delay — timing budget for isolated links
The 25 Mbps data rate supports common serial interfaces like SPI at 20 MHz clock or UART at 3 Mbps without timing margin issues. The 42 ns max propagation delay (both directions) and 2 ns max pulse-width distortion mean the isolator adds less than one clock cycle of latency at 25 MHz, which is acceptable for most sensor and control links. The 1 ns typical rise/fall times preserve signal integrity on short PCB traces.
2500 Vrms isolation and 25 kV/µs CMTI — motor-drive and inverter environments
Rated for 2500 Vrms isolation per UL 1577, the ISO7220CD provides basic insulation for equipment operating from 240 VAC mains.
