MAX14933ASE+

MAX14933ASE+ is a two-channel, 2.75kV I²C isolator. This device transfers digital signals between circuits with different power domains at ambient temperatures upto +125°C. This 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. This device features independent 2.25V to 5.5V supplies on each side of the isolator. This device operates from DC to 1.7MHz and can be used in isolated I²C busses with clock stretching. It is used in applications such as I²C, SMBus, PMBus™ interfaces, power supplies, battery management, instrumentation.
