 The MAX22563−MAX22566 are a family of 6-channel, reinforced, fast, low-power digital galvanic isolators using Maxim Integrated’s proprietary process technology. All devices feature reinforced isolation with a withstand voltage rating of 3.75kVRMS for 60 seconds. Both automotive and general-purpose devices are rated for operation at ambient temperatures from -40C to +125C.

Devices with /V suffix are AEC-Q100 qualified. See the Ordering Information for all automotive grade part numbers.

• 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.

 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.
