That data rate is the spec that catches people out: it's fine for legacy UART links at 115.2 kbps or slower, but it won't keep up with a 1 Mbps industrial bus or a high-speed debug port. If your design needs 1 Mbps or more, you're looking at a MAX3223 or a similar 3V-to-5V part with a faster slew rate. ## Supply voltage and temperature grade — the fit check If your board runs 3.3 V logic, you need a level shifter or a different transceiver like the MAX3232. The 500 mV receiver hysteresis gives you some noise margin on the RS-232 lines, which helps in electrically noisy settings.","metaTitle":"MAX232EIDWG4 RS-232 Transceiver, 250 kbps, 16-SOIC","metaDescription":"Texas Instruments MAX232EIDWG4 RS-232 transceiver, full duplex, 2/2 drivers/receivers, 250 kbps data rate, 4.5V-5.5V supply, -40°C 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":"Tube","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":"-40°C~85°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.8900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c5745de4b7b700809b3bbb20b0189163.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX232EIDWG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MAX232EIDWG4 and MAX232EIDW?","answer":"The MAX232EIDWG4 is the RoHS-compliant version of the MAX232EIDW.
