2-channel I²C isolator with 2750Vrms — what it does and where it fits
The MAX14933ASE+T is a 2-channel bidirectional digital isolator for I²C buses. It uses capacitive coupling to deliver 2750Vrms isolation between the two sides, each with 2 inputs and 2 outputs.
Key ratings and what they mean for the BOM
The 2750Vrms isolation rating provides basic isolation for 240VAC mains-referenced circuits and reinforced isolation for lower-voltage industrial field buses. The 25kV/µs common-mode transient immunity keeps I²C data intact during high dV/dt switching.
