Product Details

The MAX22663−MAX22666 are a family of 6-channel, reinforced, fast, low-power digital galvanic isolators using Analog Devices’ proprietary process technology. All devices feature reinforced isolation with a withstand voltage rating of 5kVRMS for 60 seconds. Both automotive and general-purpose devices are rated for operation at ambient temperatures from -40°C to +125°C. Devices with /V suffix are AEC-Q100 qualified. See the Ordering Information for all automotive grade part numbers.

  • Fieldbus Communications
  • Motor Control
  • Medical Systems

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, reducing system latency.

Independent 1.71V to 5.5V supplies on each side also make the devices suitable for use as level translators.

Three channels of the MAX22663 transmit digital signals in one direction, while the remaining three do in the opposite. The MAX22664 provides four channels for digital signal transmission, two of which travel in one direction and the other two in the opposite direction. The MAX22665 provides five channels for digital signal transmission in one direction and the other in the opposite direction. The MAX22666 features all six channels transmitting digital signals in one direction.
