Dual-channel capacitive isolator for industrial signal isolation
The ISO7221MD: It provides galvanic isolation up to 2500 Vrms between input and output, with one channel on side 1 and one channel on side 2. Common-mode transient immunity is specified at a minimum of 25 kV/µs, which matters when the isolator sits between a noisy motor-drive inverter and a sensitive controller. The package is an 8-pin SOIC (0.154" body width) for surface-mount assembly.
150 Mbps and 16 ns propagation delay — timing budget for SPI and UART isolation
At 150 Mbps, the 16 ns max propagation delay and 1 ns pulse-width distortion leave timing margin for SPI and UART links.
