This channel count suits multi-port serial interfaces in industrial controllers, point-of-sale terminals, or telecom line cards where one IC replaces multiple single-channel transceivers. Data rate is rated at 460 kbps — above the legacy 115.2 kbps ceiling, so the link can handle higher-speed peripherals like barcode scanners or GPS modules without bit-rate throttling. ## Supply rail and noise margin for industrial links Supply voltage is specified at 10.8V to 13.2V — a regulated 12V rail is the intended source. This is not a 3.3V or 5V part; the BOM must include a 12V regulator if the main system rail is lower. The narrow tolerance means the rail should be within ±10% of 12V nominal. Receiver hysteresis is 200 mV, which rejects noise on long RS-232 cable runs common in factory-floor or outdoor installations. ## Package and footprint considerations The 38-TFSOP package (4.40 mm body width, 0.173-inch pitch) is a fine-pitch SMT footprint. The supplier device package is listed as 38-TSSOP — confirm the land pattern matches the TFSOP dimensions in the datasheet. A 4-layer PCB with solid ground plane under the package is recommended for signal integrity at 460 kbps. For reflow soldering, the moisture sensitivity level (MSL) should be verified from the datasheet to set the correct bake and profile. ## Active lifecycle and compliance status ROHS3 compliant, so it meets current EU restriction requirements without an exemption. This reduces supply-chain risk for production builds.","metaTitle":"MAX3209EEUU+ RS-232 Transceiver, Full Duplex, 460 kbps","metaDescription":"MAX3209EEUU+ Analog Devices RS-232 transceiver, full duplex, 6 drivers/10 receivers, 460 kbps data rate, 10.8V–13.2V supply, -40°C to 85°C, 38-TFSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tube","Protocol":"RS232","Data Rate":"460Kbps","Mounting Type":"Surface Mount","Package / Case":"38-TFSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"10.8V ~ 13.2V","Receiver Hysteresis":"200 mV","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"38-TSSOP","Number of Drivers/Receivers":"6/10"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.47","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.47000","currency":"USD"},{"qty":10,"price":"$8.55200","currency":"USD"},{"qty":25,"price":"$8.15400","currency":"USD"},{"qty":100,"price":"$7.08020","currency":"USD"},{"qty":250,"price":"$6.76200","currency":"USD"},{"qty":500,"price":"$6.16534","currency":"USD"},{"qty":1000,"price":"$5.96646","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX3209E.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy MAX3209EEUU+ and get current pricing?","answer":"MAX3209EEUU+ is an active Analog Devices part.
