This is the classic MAX232 architecture — widely used in legacy serial ports, industrial terminal interfaces, and point-of-sale equipment where the system already has a 5V rail and the baud rate stays under 120 Kbps. TI no longer manufactures this specific suffix. ## Pin-compatible alternatives in the MAX232 family The MAX232DWRG4 shares the same base product number (MAX232) and 16-SOIC footprint with several active siblings. Both operate from 4.5V to 5.5V, deliver 120 Kbps, and use the same 2/2 driver/receiver configuration. If your board was laid out for the DWRG4 and you need a factory-active part, the IDR variant drops in without a PCB change — just verify the wider temperature spec is acceptable for your environment. ## Supply voltage and operating environment This transceiver is strictly a 5V part — supply range is 4.5V to 5.5V. There is no 3.3V option in this variant. Not rated for automotive or outdoor deployment.","metaTitle":"MAX232DWRG4 RS232 Transceiver, 120 Kbps, 16-SOIC, Obsolete","metaDescription":"Texas Instruments MAX232DWRG4 is a 5V RS232 transceiver with 2/2 drivers/receivers, 120 Kbps data rate, 500 mV hysteresis, 0°C to 70°C.","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":"Tape & Reel (TR)","Protocol":"RS232","Data Rate":"120Kbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Obsolete","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":"$1.3300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/952f8a8ddc00a2d59f35cc6206c49828.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX232DWRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for MAX232DWRG4?","answer":"The MAX232IDR is an active, factory-manufactured part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX232DWRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX232DWRG4 when reusing this data.
