MAX14933ASE+ by Analog Devices

Two-Channel, 2.75kVRMS I2C Isolator


The MAX14933 is a two-channel, 2.75kVRMS I2C digital isolator utilizing Maxim’s proprietary process technology. For applications requiring 5kVRMS of isolation, refer to the MAX14937 data sheet. The MAX14933 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 latch-up 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 device operates from DC to 1.7MHz and can be used in isolated I2C busses with clock stretching. The MAX14933 is available in both a 16-pin wide-body (10.3mm x 7.5mm) and narrow-body (9.9mm x 3.9mm) SOIC package. All devices are rated for operation at ambient temperatures of -40°C to +125°C.
