It operates from a 3V to 5.5V supply rail, covering both 3.3V and 5V logic domains without a separate level shifter. The part supports a 235 kbps data rate, sufficient for legacy serial ports, industrial terminal links, and configuration interfaces on embedded controllers. Industrial temperature rating (-40°C to 85°C) qualifies it for factory-floor, outdoor telecom, and engine-bay environments where commercial-grade parts would drift out of spec. ## Supply flexibility and receiver hysteresis The 3V to 5.5V supply range means the MAX3221EAE+ can be dropped into a 3.3V-only BOM or a legacy 5V RS-232 port without a regulator change. The receiver hysteresis of 300 mV provides noise immunity on longer cable runs, reducing bit errors in electrically noisy environments like motor drives or switching power supplies. ## Active production — no LTB concern The part is ROHS3 compliant.","metaTitle":"MAX3221EAE+ RS-232 Transceiver, 235 kbps, 3V–5.5V, 16-SSOP","metaDescription":"MAX3221EAE+ RS-232 transceiver, 1/1 driver/receiver, 235 kbps data rate, 3V to 5.5V supply, industrial -40°C to 85°C, 16-SSOP.
