The 250 kbps data rate is adequate for traditional UART communication up to about 115200 baud with margin; higher-speed protocols like RS-232 at 1 Mbps are outside its capability.","metaTitle":"MAX3232ECDE4 RS-232 Transceiver, 250 kbps, 16-SOIC","metaDescription":"Texas Instruments MAX3232ECDE4 RS-232 transceiver, 2/2 drivers/receivers, 250 kbps data rate, 3V to 5.5V supply, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tube","Protocol":"RS232","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Base Product Number":"MAX3232","Receiver Hysteresis":"300 mV","Operating Temperature":"0°C~70°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dabd420645ea94ffbcfa5f91c9a9291d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232ECDE4/alternatives.json"},"ai":{"faq":[{"question":"Is MAX3232ECDE4 obsolete and are there alternative parts?","answer":"Yes, MAX3232ECDE4 is listed as Obsolete. No direct pin-compatible replacement is listed in the official records, but the MAX3232 family includes many active variants (e.g., MAX3232E, MAX3232C) that share the same 16-SOIC footprint and 2/2 driver/receiver count. Verify the exact supply voltage and temperature grade against your BOM before substituting."},{"question":"Can I use MAX3232ECDE4 at 3.3V and what is its data rate?","answer":"Yes, the MAX3232ECDE4 operates from 3V to 5.5V, so a 3.3V rail is within spec. The data rate is 250 kbps, which covers standard UART speeds up to 115200 baud with margin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX3232ECDE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX3232ECDE4 when reusing this data.
