Introduction

The MAX22163−MAX22166 are a family of six-channel, reinforced, fast, low-power digital galvanic isolators using proprietary process technology. All devices feature reinforced isolation with a withstand voltage rating of 3kVRMS for 60 seconds. Both automotive and general-purpose devices are rated for operation at ambient temperature from -40°C to +125°C. These devices 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 with 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.
