It handles point-to-point or multi-drop serial communication at data rates up to 250 kbps over the standard 4.5 V to 5.5 V supply rail. The 500 mV of receiver hysteresis filters line noise on longer cable runs, which matters when the serial link leaves the backplane and enters a factory-floor harness. Rated for -40°C to 85°C, this part is at home in industrial control, telecom line cards, and instrumentation where a reliable RS-232 port is needed without external charge-pump capacitors. ## 250 kbps data rate — what it means for the bus The full-duplex architecture means the transmitter and receiver paths run independently, so a terminal server or PLC serial port can send and receive simultaneously without bus-turnaround dead cycles. ## Active production — no LTB pressure The MAX222EWN+ carries an Active lifecycle status and ROHS3 compliance. There is no last-time-buy notice or NRND flag on this order code.","metaTitle":"MAX222EWN+ RS-232 Transceiver, Full Duplex, 250 kbps","metaDescription":"MAX222EWN+ RS-232 transceiver from Maxim Integrated.
