The 300 mV receiver hysteresis cleans up noisy lines, common in industrial cable runs.
ROHS3 compliant.
The 3V to 5.5V supply range means it can run from a regulated 3.3V rail or a legacy 5V bus without a separate regulator — one less line item on the BOM.
The MAX3222ECDB supports a data rate of 500 kbps.
Yes. The supply voltage range is 3V to 5.5V, so the part operates directly from a 3.3V rail and its logic inputs are compatible with 3.3V CMOS levels.
