The supply scheme is dual-rail: a 5V logic rail plus a separate 7.5V to 13.2V charge-pump input for the RS232 driver outputs, which means the board must carry both voltages rather than relying on a single 5V rail with an internal doubler. ## Package and temperature grade — SOIC-16 wide body, -40 to 85°C Housed in a 16-SOIC wide-body package (7.50 mm body width), the MAX231EWE+ uses the standard RS232 transceiver footprint — the 0.295-inch width matches the common SOIC-16W land pattern used across the industry for dual-channel parts. Receiver hysteresis is specified at 500 mV, providing noise immunity on the RS232 bus lines in electrically noisy environments — a typical industrial backplane sees conducted noise in the 200-400 mV range, so the 500 mV threshold reduces false triggering without external filtering. ## Compliance and sourcing — ROHS3, no exemptions, quoted to order ROHS3 compliant (2015/863/EU) with no exemptions listed — the part ships without lead, mercury, cadmium, or the four phthalates, clearing EU and UKCA market entry without additional documentation.","metaTitle":"MAX231EWE+ RS232 Transceiver, 120Kbps, 2/2, SOIC-16","metaDescription":"MAX231EWE+ RS232 transceiver from Analog Devices, full duplex 2/2 driver/receiver, 120Kbps data rate, 5V/7.5-13.2V supply, -40 to 85°C, SOIC-16.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tube","Protocol":"RS232","Data Rate":"120Kbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"5V, 7.5V ~ 13.2V","Receiver Hysteresis":"500 mV","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.68","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.68000","currency":"USD"},{"qty":10,"price":"$7.83900","currency":"USD"},{"qty":25,"price":"$7.47440","currency":"USD"},{"qty":100,"price":"$6.49010","currency":"USD"},{"qty":250,"price":"$6.19836","currency":"USD"},{"qty":500,"price":"$5.65146","currency":"USD"},{"qty":1000,"price":"$4.92224","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What supply voltages does the MAX231EWE+ require?","answer":"It needs two supply rails: a 5V logic supply and a separate 7.5V to 13.2V input for the RS232 driver charge pump — the board must provide both, not just a single 5V rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX231EWE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX231EWE when reusing this data.
