The MAX22245/MAX22246 are a family of 2-channel reinforced, fast, low-power digital galvanic isolators using Analog Devices' proprietary process technology. All devices feature reinforced isolation for a withstand voltage rating of 5kVRMS 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. Refer to the Ordering Information for all automotive grade part numbers.

• Fieldbus Communications

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.

Devices are available with a maximum data rate of 25Mbps or 200Mbps, and with outputs that are either default high or default low. The devices 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 MAX22245 features two channels transferring data in the same direction. The two channels of the MAX22246 transfer data in opposite directions, and this makes the MAX22246 ideal for isolating the Tx and Rx lines of a transceiver.
