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.
