The MAX22563−MAX22566 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 3.75kVRMS for 60s. Both automotive
and general-purpose devices are rated for operation at
ambient temperatures from -40°C to +125°C.
SSOP
Devices are available with a maximum data rate of either
25Mbps or 200Mbps and with user-selectable default-
high or default-low outputs. The devices feature low
propagation delay and low clock jitter, which reduces
system latency.
Independent 1.71V to 5.5V supplies on each side also
make the devices suitable for use as level translators.
Devices with /V suffix are AEC-Q100 qualified. See the
Ordering Information for all automotive grade part
numbers.
The MAX22563 features three channels transmitting
signals in one direction and three in opposite; the
MAX22564 offers four channels transmitting signals in
one direction and two in opposite; the MAX22565
provides five channels transmitting signals in one
direction and one in opposite; the MAX22566 features
all six channels transmitting signals in one direction.
Industrial
•
• 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.
