It won't support the higher bit rates some newer RS-232 parts push (1 Mbps), but for the vast majority of industrial serial links — PLC programming ports, barcode scanners, serial consoles — 250 kbps is plenty. The receiver hysteresis of 300 mV cleans up noise on longer cable runs, which helps avoid bit errors on a factory floor. ## Supply flexibility and 3.3 V compatibility A 3.3 V-only MCU can drive the MAX3232EIDWR directly — no extra regulator, no level translation on the logic side. The charge-pump circuitry generates the RS-232 voltage levels internally, so the only external components are four small capacitors. This keeps the BOM simple and the board area tight. That means no end-of-life notice on the horizon, no last-time-buy scramble.","metaTitle":"MAX3232EIDWR RS-232 Transceiver, 250 kbps, 3-5.5V, SOIC-16","metaDescription":"MAX3232EIDWR is a full-duplex RS-232 transceiver with 2/2 drivers/receivers, 250 kbps data rate, 3V to 5.5V supply, -40°C to 85°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS232","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Base Product Number":"MAX3232","Receiver Hysteresis":"300 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dabd420645ea94ffbcfa5f91c9a9291d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232EIDWR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MAX3232EIDWR?","answer":"Within the same family, the MAX3232EID (non-wide-body SOIC) is functionally identical but in a narrower 16-SOIC package (3.9 mm width vs 7.5 mm).
