The 120 kbps data rate is the classic original MAX232 speed — fine for 115200 baud and slower legacy equipment, but not a match for the 1 Mbps capable MAX232A if you're pushing higher-throughput links. Supply range is 4.5V to 5.5V, so it's strictly a 5V rail part; don't try to run it off 3.3V without a boost converter. It belongs in office equipment, point-of-sale terminals, lab instruments, and other indoor gear. Housed in a 16-SOIC wide-body (7.50 mm width), surface-mount only. The wide-body footprint is less common than the narrow SOIC-16 (3.90 mm), so double-check your PCB land pattern before layout — a narrow pad set won't fit this part. Ships in tube, not tape-and-reel, which matters if your pick-and-place feeder expects a reel; you'll need to transfer to a compatible carrier or hand-place for low-volume builds. The base number MAX232 has been second-sourced by multiple manufacturers for decades, so supply depth is good even if TI's own fab runs tight.","metaTitle":"MAX232DWG4 RS-232 Transceiver, 120 kbps, 16-SOIC","metaDescription":"MAX232DWG4 is a 5V RS-232 transceiver with 2/2 drivers/receivers, full duplex, 120 kbps data rate, 500 mV hysteresis, 16-SOIC package, 0°C to 70°C.","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":"Tube","Protocol":"RS232","Data Rate":"120Kbps","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":"$1.6000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/952f8a8ddc00a2d59f35cc6206c49828.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX232DWG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MAX232 and MAX232A?","answer":"The key difference is data rate: the MAX232DWG4 is rated at 120 kbps, while the MAX232A typically supports 230 kbps or 1 Mbps depending on the variant. The MAX232A also uses smaller external charge-pump capacitors (0.1 µF vs 1.0 µF) and has tighter driver output swing. Pinout and package are identical, so a swap is straightforward if your firmware can handle the higher speed."},{"question":"Is MAX232DWG4 RoHS compliant?","answer":"The 'G4' suffix in the order code indicates TI's green/RoHS-compliant lead-free finish.
