At 250 kbps the part comfortably covers standard RS232 applications like debug UARTs, modem control, and point-of-sale terminal interfaces. The 500 mV hysteresis on the receiver inputs helps maintain a clean logic level on longer cable runs or in electrically noisy environments typical of commercial enclosures. If your design needs faster throughput — say 1 Mbps for a high-speed industrial link — this part won't close timing; the MAX3222 family is the next step up. ## Package and supply — board-fit notes The 16-SOIC wide-body (7.50 mm width) footprint is a common RS232 transceiver layout, shared with the original MAX232 and many second-source equivalents. This is a mature, widely second-sourced RS232 transceiver — the base MAX232 pinout is supported by multiple vendors, which simplifies dual-sourcing for supply resilience.","metaTitle":"MAX232ECDWRE4 RS232 Transceiver, 250kbps, 2/2 Drivers","metaDescription":"Texas Instruments MAX232ECDWRE4 RS232 transceiver, full duplex, 250kbps data rate, 2/2 drivers/receivers, 4.5V-5.5V supply, 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)","Protocol":"RS232","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm 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/c5745de4b7b700809b3bbb20b0189163.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX232ECDWRE4/alternatives.json"},"ai":{"faq":[{"question":"Is MAX232ECDWRE4 a direct replacement for the original MAX232?","answer":"Yes, the MAX232ECDWRE4 is a direct pin-compatible replacement for the original MAX232 in the 16-SOIC wide-body footprint."},{"question":"What is the data rate of MAX232ECDWRE4?","answer":"The MAX232ECDWRE4 supports a data rate of 250 kbps, which is the standard speed for the MAX232 family and covers most RS232 applications like debug UARTs and modem control."},{"question":"Is MAX232ECDWRE4 obsolete?","answer":"It remains a current, manufacturable part for new designs and production runs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX232ECDWRE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX232ECDWRE4 when reusing this data.
