Introduction

MAX22440/MAX22441/MAX22442, MAX22840/MAX22841/MAX22842, and MAX22880/MAX22881/MAX22882 are a family of 4-channel, enhanced, ultra-low-power digital current isolators manufactured using proprietary process technology. The MAX22440–MAX22442 are available in a 16-QSOP package with a withstand voltage rating of 3kVRMS (for 60 seconds); the MAX22840–MAX22842 are available in a 16-wide-body SOIC package with a withstand voltage rating of 5kVRMS (for 60 seconds); the MAX22880–MAX22882 are available in a 20-SSOP package with a withstand voltage rating of 3.75kVRMS (for 60 seconds). The devices are rated for an operating ambient temperature range of -40°C to +125°C. These devices transfer digital signals between circuits in different power domains, consuming as little as 77.04µW per channel at 1Mbps (1.8V supply). The ultra-low-power characteristics reduce system power consumption, improve reliability, and enable compact designs. The devices support data rates up to 10Mbps and offer default-high or default-low output options. Low propagation delay and low pulse-width distortion help reduce system latency. Independent 1.71V to 5.5V supplies on both sides also make the devices suitable for use as level translators. All four channels of the MAX22440/840/880 share the same data direction. The MAX22441/841/881 feature three channels in one direction and one channel in the opposite direction. The MAX22442/842/882 feature two channels in each direction.
