Four-Channel, Fast, Low-Power, 5kVRMS Digital Isolators


  • Low Power Consumption
  • 25Mbps or 200Mbps
  • Robust Galvanic Isolation
  • three possible unidirectional channel configurations

One of the Industry's Fastest Low Power Digital Isolators

The MAX14434–MAX14436 are among the fastest, lowest power, 4-channel, digital galvanic isolators on the market today using Maxim’s proprietary process technology. These devices transfer digital signals between circuits with different power domains while using as little as 0.58mW per channel at 1Mbps with a 1.8V supply. The MAX14434/5/6 have an isolation rating of 5kVRMS for 60 seconds.
