The MAX22290/MAX22291 is a family of 2-channel reinforced, fast, low-power digital galvanic isolators using Maxim’s proprietary process technology. All devices feature reinforced isolation for a withstand voltage rating of 3kVRMS for 60 seconds. Both automotive and general-purpose devices are rated for operation at ambient temperatures of -40°C to +125°C.
Devices with /V suffix are AEC-Q100 qualified. See the Ordering Information table for all automotive grade part numbers.

These devices transfer digital signals between circuits with different power domains, using as little as 0.78mW per channel at 1Mbps (1.8V supply). The low-power feature reduces system dissipation, increases reliability, and enables compact designs.
The devices are available with a maximum data rate of 25Mbps or 200Mbps, and with outputs that are either default high or default low. They feature low propagation delay and low clock jitter, which reduces system latency. Independent 1.71V to 5.5V supplies on each side of the isolator also make the devices suitable for use as level translators.
The MAX22290 features two channels transferring data in the same direction. The two channels of the MAX22291 transfer data in opposite directions, and this makes the MAX22291 ideal for isolating the Tx and Rx lines of a transceiver.
