It delivers a guaranteed 5 Mbps data rate across a 2500 Vrms isolation barrier, which covers the majority of isolated SPI, UART, and GPIO signal paths in industrial and automotive systems. The 2/0 input/output channel configuration means both channels drive from side 1 to side 2, so this part handles two downstream signals per package — no bidirectional lanes. The 70 ns propagation delay (max) and 3 ns pulse-width distortion give enough timing margin for 5 Mbps clocked interfaces, but if you are pushing toward 10 Mbps or need a bidirectional channel, you are looking at a different isolator family. The 25 kV/µs common-mode transient immunity is the rating that makes this part at home in motor-drive and inverter environments where fast-switching nodes couple noise across the barrier.","metaTitle":"ISO7220BD General Purpose Digital Isolator, 5 Mbps","metaDescription":"TI ISO7220BD dual-channel digital isolator: 5 Mbps data rate, 2500 Vrms isolation, capacitive coupling, -40°C to 125°C.

For faster SPI or bidirectional signals, check the ISO7221 or ISO7240 families."},{"question":"What is the equivalent of ISO7220BD?","answer":"Pin-compatible alternatives within the same TI family include the ISO7220B (same data rate, different output enable logic) and the ISO7221 (one reverse channel).
