The MAX14937 is a two-channel, 5kVRMS I2C digital isolator utilizing Maxim’s proprietary process technology. For applications requiring 2.75kVRMS of isolation, see the MAX14933 data sheet. The device transfers digital signals between circuits with different power domains at ambient temperatures up to +125°C.

The device offers two bidirectional, open-drain channels for applications, such as I2C, that require data to be transmitted in both directions on the same line. To prevent latchup action, the A-side outputs comprise special buffers that regulate the logic-low voltage at 0.9V (max), and the input logic-low threshold is at least 50mV lower than the output logic-low voltage. The B side features conventional buffers that do not regulate logic-low output voltage.

The device features independent 2.25V to 5.5V supplies on each side of the isolator. The MAX14937 operates from DC to 1.7MHz and can be used in isolated I2C busses with clock stretching.

The MAX14937 is available in a 16-pin, wide-body (10.3mm x 7.5mm) SOIC package, and is rated for operation at ambient temperatures of -40°C to +125°C.
