The 300 mV receiver hysteresis provides noise rejection on longer cable runs, which is where RS-232 links typically pick up ground offset and crosstalk. The 20-SOIC wide-body (7.50 mm width) is a common footprint; the 1.27 mm pitch makes hand-assembly and inspection straightforward.","metaTitle":"MAX3222IDWR RS-232 Transceiver, 250 kbps, 20-SOIC","metaDescription":"TI MAX3222IDWR RS-232 transceiver, full duplex 2/2, 3V to 5.5V supply, 250 kbps data rate, -40°C to 85°C, 20-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS232","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Base Product Number":"MAX3222","Receiver Hysteresis":"300 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"20-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4000","priceTiers":[{"qty":1,"price":"$2.40000","currency":"USD"},{"qty":10,"price":"$2.15200","currency":"USD"},{"qty":25,"price":"$2.03000","currency":"USD"},{"qty":100,"price":"$1.72950","currency":"USD"},{"qty":250,"price":"$1.62392","currency":"USD"},{"qty":500,"price":"$1.42092","currency":"USD"},{"qty":1000,"price":"$1.17734","currency":"USD"},{"qty":2000,"price":"$1.14900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2dd0c720be57623e93e05eecf9ce44ce.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3222IDWR/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of MAX3222IDWR and can it handle 115200 baud?","answer":"The MAX3222IDWR is rated for 250 kbps, which is over double the 115200 baud rate. It handles that common serial speed with comfortable margin, even with the receiver hysteresis set at 300 mV for noise immunity."},{"question":"Is MAX3222IDWR compatible with 5V supply or only 3.3V?","answer":"It accepts a supply range of 3V to 5.5V, so it works on both 3.3V and 5V rails without modification."},{"question":"What is the closest pin-compatible alternative to MAX3222IDWR?","answer":"Within the MAX3222 family, the MAX3222IDB (16-SOIC) is a narrower package variant but not pin-compatible due to different body width. The MAX3222ECUP (20-TSSOP) offers the same 2/2 driver/receiver count in a smaller footprint but requires a layout change. For a direct drop-in, stay with the 20-SOIC wide-body variants sharing the same base number."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX3222IDWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX3222IDWR when reusing this data.
