MAX22346CAAP+                               Description

The MAX22344–MAX22346 are reinforced, fast, lowpower 4-channel digital galvanic isolators using Maxim’s proprietary process technology. These devices transfer digital signals between circuits with different power domains, using as little as 0.74mW per channel at 1Mbps (1.8V supply). All of the devices in the family feature reinforced isolation for a withstand voltage rating of 3.75kVRMS for 60 seconds.
