These devices transfer digital signals between circuits with different power domains, using as little as 0.78mW per channel at 1Mbps (1.8V supply). The low-power feature reduces system dissipation, increases reliability, and enables compact designs. The devices are available with a maximum data rate of 25Mbps or 200Mbps, and with outputs that are either default high or default low. Each device features low propagation delay and low clock jitter, which reduces system latency. Independent 1.71V to 5.5V supplies on each side of the isolator make the devices suitable for level translators.
The Analog Devices MAX22290 features two channels transferring data in the same direction. The two channels of the MAX22291 transfer data in opposite directions, making the MAX22291 ideal for isolating the Tx and Rx lines of a transceiver.
