If this part is on your BOM, you need to secure your lifetime buy or qualify a drop-in replacement before supply dries up. ## What the MAX3232IDR is — a 3V–5.5V RS-232 transceiver in 16-SOIC The data rate is 250kbps, adequate for standard UART communication in industrial control, point-of-sale terminals, and telecom equipment. ## 16-SOIC package — what it means at the bench The MAX3232IDR comes in a 16-SOIC (3.90mm width) package. That's a standard footprint — easy to hand-solder or reflow. The 1.27mm pin pitch gives good clearance for routing the RS-232 lines and decoupling caps. If you're doing a rework, the SOIC body lifts clean with hot air at 300°C for about 30 seconds; the 0.154-inch width means the nozzle can hit both rows without cooking adjacent parts. ## Supply voltage range — 3V to 5.5V, no extra regulator needed The supply range spans 3V to 5.5V, so this transceiver works directly off a 3.3V rail or a 5V rail without a separate LDO. That simplifies the power tree in mixed-voltage designs — one less part to source. The wide range also helps during power-up sequencing: the part powers up cleanly as the rail ramps, no brownout glitches on the serial lines.","metaTitle":"MAX3232IDR RS-232 Transceiver, 250kbps, 16-SOIC, Last Buy","metaDescription":"Texas Instruments MAX3232IDR RS-232 transceiver, full duplex, 2/2 drivers/receivers, 250kbps data rate, 3V to 5.5V supply, -40°C to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","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 (0.154\\\", 3.90mm Width)","Product Status":"Last Time Buy","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":"$1.1385","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd1772ada4594b24defcd65402aeacba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232IDR/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the MAX3232IDR?","answer":"The MAX3232IDR is in Last Buy status. We source it through independent distribution channels. Submit an RFQ — we confirm current availability and pricing at quote time. No stock or price figures are published here because the market moves daily on end-of-life parts."},{"question":"What is the difference between MAX3232IDR and MAX3232ID?","answer":"The MAX3232IDR is the tape-and-reel packaged version of the MAX3232ID. The 'R' suffix indicates reel packaging. The difference is only the shipping medium: the IDR comes on a reel for automated pick-and-place assembly; the ID ships in tubes or trays."},{"question":"Can MAX3232IDR be used with a 3.3V supply?","answer":"Yes. The MAX3232IDR operates from 3V to 5.5V, so a 3.3V rail is within the specified range. At 3.3V the device still meets the RS-232 output voltage levels (±5V minimum) and the 250kbps data rate. No external level shifting is needed when interfacing a 3.3V UART to a ±12V RS-232 bus."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX3232IDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX3232IDR when reusing this data.
