If your board runs on 3.3V logic, you need a different RS232 part (like the MAX3232 family) that integrates a charge-pump for 3.3V operation. The MAX232DRE4's charge pump generates the ±10V RS232 levels from the 5V input, but it won't start reliably below about 4.5V. ## Temperature grade: commercial, not industrial If your application sees freezing or hot ambient conditions, look at the extended-temperature variants in the MAX232 family.","metaTitle":"TI MAX232DRE4 RS232 Transceiver, 120 kbps, 16-SOIC","metaDescription":"Texas Instruments MAX232DRE4 RS232 transceiver, 2/2 driver/receiver, full duplex, 120 kbps data rate, 4.5V to 5.5V supply, 16-SOIC package.","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)","Protocol":"RS232","Data Rate":"120Kbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"MAX232","Receiver Hysteresis":"500 mV","Operating Temperature":"0°C~70°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/952f8a8ddc00a2d59f35cc6206c49828.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX232DRE4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MAX232DRE4 and MAX232CSE?","answer":"For an extended-temperature environment, choose the CSE suffix."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX232DRE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX232DRE4 when reusing this data.
