The MAX22440-MAX22442, MAX22840-MAX22842, and
MAX22880-MAX22882 are a family of 4-channel,
reinforced, ultra-low-power digital galvanic isolators using
Analog Devices proprietary process technology. The
MAX22440-MAX22442 are in a 16-QSOP package with a
withstand voltage rating of 3kVRMS for 60 seconds, the
MAX22840-MAX22842 are in a 16 wide SOIC package
with a withstand voltage rating of 5kVRMS for 60 seconds,
and the MAX22880-MAX22882 are in a 20-SSOP
package with a withstand voltage rating of 3.75kVRMS for
60 seconds. Devices are rated for operation at ambient
temperatures from -40°C to +125°C.
The devices transfer digital signals between circuits with
different power domains, using as little as 77.04μW per
channel at 1Mbps (1.8V supply). The ultra-low-power
feature reduces system dissipation, increases reliability,
and enables compact designs. Devices are available with
a maximum data rate of 10Mbps and with 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. All
four channels of the MAX22440/840/880 transfer data in
the same direction. Three out of four channels of the
MAX22441/841/881 transfer data in one direction while
the other one transfers data in the opposite direction. Two
channels of the MAX22442/842/882 transfer data in one
direction and the other two in the opposite direction.
