General Description：

The MAX14937 is a two-channel, 5kVRMS I²C digital isolator utilizing Maxim’s proprietary process technology. For applications requiring 2.75kV_RMS 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.
