5 Mbps capacitive-coupled isolator in an 8-SOIC
The two channels are unidirectional, with both inputs on side 1 and no inputs on side 2 — a 2/0 channel configuration suited for isolating a single-direction data path like a SPI clock and data line or a pair of control signals.
70 ns propagation delay — budget it in the timing closure
Maximum propagation delay is 70 ns in both directions, with a pulse-width distortion of 3 ns max. At 5 Mbps the bit period is 200 ns, so the 70 ns delay consumes about 35% of the timing budget — workable for most industrial serial links, but tight for a daisy-chained SPI bus running at full speed. The 1 ns typical rise/fall time means the signal edges are fast; the layout needs controlled impedance if the trace runs more than a few inches.
The base product number is ISO7220, which covers the whole family of dual-channel isolators with different speed and input-configuration options.
