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.  
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.  
Industrial

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.
