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.

• Isolated SPI, RS-232/422/485, CAN, Digital I/O
• 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.
