No external ±12V supply is required. The 300 mV of receiver hysteresis prevents chatter on the RX line when the cable picks up noise — useful in industrial environments where the serial cable runs through a motor drive bay. The 16-SOIC footprint is a common PCB land pattern, so layout reuse across projects is straightforward. ## Lifecycle status For dual-sourcing flexibility, the MAX3232 family includes several package and temperature variants; the EIDR suffix denotes the industrial-temperature, SOIC-16, tape-and-reel option.","metaTitle":"MAX3232EIDR RS-232 Transceiver, 250kbps, 3V-5.5V, 16-SOIC","metaDescription":"Texas Instruments MAX3232EIDR 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":"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 (0.154\\\", 3.90mm 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/MAX3232EIDR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MAX3232EIDR?","answer":"Within the same family, the MAX3232ECPWR is a pin-compatible alternative in a TSSOP-16 package. The EIDR uses the SOIC-16 footprint, so the package difference matters for board layout. Both share the same 2/2 driver/receiver count, 250kbps data rate, and 3V to 5.5V supply range."},{"question":"Can MAX3232EIDR handle 5V?","answer":"Yes, the supply range is 3V to 5.5V, so it works on a 5V rail directly. The charge pump generates the RS-232 voltage levels from the 5V supply without external components."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX3232EIDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX3232EIDR when reusing this data.
