The 300 mV receiver hysteresis cleans up noisy RS-232 lines — useful when the cable picks up motor-drive hash or passes near a switching supply.","metaTitle":"MAX3222ECDW RS-232 Transceiver, 500 kbps, 20-SOIC","metaDescription":"TI MAX3222ECDW RS-232 transceiver: full duplex, 2/2 drivers/receivers, 500 kbps, 3V to 5.5V supply, 20-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":"500kbps","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":"0°C~70°C","Supplier Device Package":"20-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/445041c92021f26997981b64349fda77.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3222ECDW/alternatives.json"},"ai":{"faq":[{"question":"MAX3222ECDW vs MAX3222E: what is the difference?","answer":"The MAX3222ECDW is the 20-SOIC wide-body variant of the MAX3222E family. The base part number MAX3222E covers multiple package options; the 'DW' suffix specifically designates the 20-SOIC (0.295\", 7.50mm width) surface-mount package. Electrical specs — 2/2 drivers/receivers, 500 kbps, 3V to 5.5V supply — are identical across the family."},{"question":"Does MAX3222ECDW require external charge pump capacitors?","answer":"Yes. Like most RS-232 transceivers, the MAX3222ECDW uses an internal charge pump to generate the ±5.5V RS-232 levels from the single supply, and it requires external capacitors — typically four 0.1 µF to 1 µF ceramic caps — connected to the charge-pump pins. The exact values and pin connections are in the datasheet."},{"question":"Is MAX3222ECDW compatible with 3.3V logic?","answer":"Yes. The 3V to 5.5V supply range includes 3.3V, and the logic inputs are 3.3V-compatible. At 3.3V VCC the part drives RS-232 output levels and accepts 3.3V logic inputs without extra level translation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX3222ECDW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX3222ECDW when reusing this data.
