Maxim Integrated MAX22290/MAX22291 Two-Channel Digital Isolators are a family of 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. The parts with a /V suffix are AEC-Q100 qualified. 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. Each device features low propagation delay and low clock jitter, which reduces system latency. Independent 1.71V to 5.5V supplies on each side of the isolator make the devices suitable for level translators.
