Introduction

The MAX22420/1, MAX22820/1 are a family of 2-channel, reinforced, ultra-low-power digital galvanic isolators using Analog Devices’ proprietary process technology. The MAX22420/1 feature reinforced isolation with a withstand voltage rating of 3kVRMS for 60 seconds. The MAX22820/1 feature reinforced isolation with a withstand voltage rating of 5kVRMS for 60 seconds. 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 90.7μW per channel at 1Mbps (1.8V supply). The ultra-low-power feature reduces system dissipation, increases reliability, and enables compact designs. Devices are available with a glitch rejection filter of either 29ns or 70ns (typ) 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. The MAX22420/MAX22820 feature two channels transferring data in the same direction. The two channels of the MAX22421/MAX22821 transfer data in opposite directions.
