With a supply range of 3V to 5.5V, this part works on a 3.3V rail directly — no extra regulator needed. The receiver hysteresis of 300 mV cleans up noisy RS-232 lines, which matters when the cable runs through a plant floor with motor drives nearby.
ROHS3 compliant, which keeps it clear of the RoHS exemption deadlines.
