The data rate is specified at 120Kbps, and the receiver hysteresis is 500 mV for noise rejection on the line. ## 5V-only supply — plan for level translation if mixing 3.3V logic It does not accept a 3.3V supply, and the RS232 driver outputs swing to the supply rails. If the connected UART is 3.3V-logic, the receiver outputs (TTL side) will also swing to 5V — an external level shifter or resistive divider may be needed to avoid overvoltage on the 3.3V side. The 120Kbps data rate is adequate for legacy serial protocols (9600 baud, 115200 baud) but not for high-speed RS232 applications.","metaTitle":"MAX232DWE4 RS232 Transceiver, 120Kbps, 16-SOIC, Active","metaDescription":"MAX232DWE4 is an active RS232 full-duplex transceiver from Texas Instruments. 2/2 drivers/receivers, 120Kbps data rate, 4.5V~5.5V supply, 0°C~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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/952f8a8ddc00a2d59f35cc6206c49828.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX232DWE4/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum data rate of MAX232DWE4?","answer":"The MAX232DWE4 is specified for a data rate of 120Kbps.
