The 120 kbps data rate is the classic original MAX232 speed — fine for terminal interfaces, industrial HMI panels, and legacy serial links that never pushed past 115.2 kbps. The 500 mV receiver hysteresis gives clean edge detection on noisy lines without external schmitt triggers. ## Supply and temperature — fit for the floor No 3.3 V option here — if your board is mixed-voltage, you will need a separate 5 V supply or a level translator. The 16-SOIC footprint is a standard, rework-friendly package — easy to swap in the field with a soldering iron and some wick. ## Lifecycle and sourcing — no rush, but plan your lane It is a mature, widely second-sourced part — the MAX232 function is a de facto standard. For dual-sourcing resilience, the generic MAX232 or MAX232ID (same pinout, same speed) from any major house will drop in.","metaTitle":"MAX232IDRG4 RS232 Transceiver, 120 kbps, 2/2 Driver/Receiver","metaDescription":"Texas Instruments MAX232IDRG4 RS232 full-duplex transceiver, 120 kbps data rate, 2/2 drivers/receivers, 5 V 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":{"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":"-40°C~85°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/MAX232IDRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of MAX232IDRG4?","answer":"The MAX232IDRG4 is rated for 120 kbps.
