Analog Devices / Maxim Integrated MAX22563−MAX22566 Digital Isolators

Analog Devices MAX22563−MAX22566 is a family of 6-channel, reinforced, fast, low-power digital galvanic isolators using proprietary process technology. All devices feature reinforced isolation with a withstand voltage rating of 3.75kVRMS for 60 seconds. Both automotive and general-purpose devices are rated for operation at ambient temperatures from -40°C to +125°C. These Analog Devices modules transfer digital signals between circuits with different power domains, using as little as 0.71mW 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 either 25Mbps or 200Mbps and user-selectable default-high or default-low outputs. The devices feature low propagation delay and low clock jitter, which reduces system latency.

Independent 1.71V to 5.5V supplies on each side also make the devices suitable for use as level translators. The MAX22563 features three channels transmitting signals in one direction and three in the opposite direction. The MAX22564 offers four channels transmitting signals in one direction and two in the opposite direction. The MAX22565 provides five channels transmitting signals in one direction and one in the opposite direction. The Analog Devices MAX22566 features all six channels transmitting signals in one direction. The devices with a /V suffix are AEC-Q100 qualified.
