At 120 kbps, this transceiver covers standard UART baud rates up to 115200 without margin issues. If your design needs 250 kbps or 1 Mbps RS232, this part won't get there — you'd step to a MAX3223 or similar. For most PLCs, barcode scanners, and serial printers, 120 kbps is plenty. ## Sourcing and lifecycle: no obsolescence worry That means it's still a safe line-item for new production builds and repair stock alike. ## Package and footprint: 16-SOIC wide-body Housed in a 16-SOIC with 7.50 mm body width (the wide-body variant), the MAX232IDWG4 uses the same footprint as the MAX232IDR (narrow-body 3.90 mm) but with a wider pad pitch — verify your board's land pattern before swapping. Surface-mount only, shipped in tube.","metaTitle":"MAX232IDWG4 RS232 Transceiver, 120 kbps, 16-SOIC","metaDescription":"TI MAX232IDWG4 RS232 transceiver, 2/2 drivers/receivers, 120 kbps, 5V supply, industrial temp -40 to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Type":"Transceiver","Duplex":"Full","Series":"-","Protocol":"RS232","Data Rate":"120Kbps","Packaging":"Tube","Part Status":"Obsolete","Manufacturer":"Texas Instruments","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":"-40°C ~ 85°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/952f8a8ddc00a2d59f35cc6206c49828.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX232IDWG4/alternatives.json"},"ai":{"faq":[{"question":"Does MAX232IDWG4 support a 5V supply?","answer":"Yes, the supply range is 4.5V to 5.5V, so a regulated 5V rail is exactly what it needs.
