Dual-channel digital isolator for industrial signal isolation
It supports a maximum data rate of 5Mbps, making it suitable for isolating SPI, UART, and CAN bus signals in motor drives, PLCs, and industrial sensor interfaces.
70ns propagation delay — budget for closed-loop timing
The 1ns typical rise/fall time keeps signal integrity clean at 5Mbps without excessive edge-rate ringing.
25kV/µs CMTI — stays clean in noisy environments
A minimum common-mode transient immunity of 25kV/µs means the output won't glitch when high dV/dt transients couple across the isolation barrier. This is critical in motor-drive inverters, solar inverters, and any application where fast-switching power stages share a ground reference with the control side.
The base product number ISO7221 covers a family of speed and channel-configuration variants, simplifying BOM consolidation if you need a different data rate or channel count in the same footprint.
8-SOIC package — board area and storage notes
Housed in an 8-SOIC (0.154", 3.90mm width) surface-mount package, this isolator fits standard SOIC-8 land patterns.
