The receiver hysteresis of 300 mV provides noise immunity on the bus, reducing bit errors in electrically noisy environments. Buyers should verify the exact suffix for their BOM, as variations exist for different temperature grades or package options.","metaTitle":"MAX3222CDBRG4 RS-232 Transceiver, 250 kbps, 20-SSOP","metaDescription":"Texas Instruments MAX3222CDBRG4 is an active RS-232 transceiver with full-duplex 2/2 driver/receiver, 3V to 5.5V supply, 250 kbps data rate, 20-SSOP.","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":"250kbps","Mounting Type":"Surface Mount","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Base Product Number":"MAX3222","Receiver Hysteresis":"300 mV","Operating Temperature":"0°C~70°C","Supplier Device Package":"20-SSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2dd0c720be57623e93e05eecf9ce44ce.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3222CDBRG4/alternatives.json"},"ai":{"faq":[{"question":"Can MAX3222CDBRG4 be used at 5V supply?","answer":"Yes, the supply range of 3V to 5.5V covers both 3.3V and 5V rails, making it compatible with standard logic levels without additional regulation."},{"question":"Is MAX3222CDBRG4 compatible with 3.3V systems?","answer":"Yes, the device operates from a 3V minimum supply, so it works directly on a 3.3V rail while still meeting RS-232 output levels."},{"question":"What is the closest pin-compatible alternative to MAX3222CDBRG4 in this component family?","answer":"The MAX3222 family includes multiple temperature and package variants. The MAX3222CDBR (without the 'G4' suffix) is functionally equivalent in the same 20-SSOP package, differing only in lead-free/RoHS compliance marking.
