The MAX2216x family has reinforced isolation with a withstand voltage rating of 3kVRMS for 60 seconds. Both automotive and general-purpose devices are rated for operation at ambient temperatures from -40°C to +125°C. Devices with /V suffix are AEC-Q100 qualified.
- 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 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.
- The MAX22163 features three channels transmitting digital signals in one direction and three in opposite.
- The MAX22164 offers four channels transmitting digital signals in one direction and two in opposite.
- The MAX22165 provides five channels transmitting digital signals in one direction and one in opposite.
- The MAX22166 features all six channels transmitting digital signals in one direction.
