No extra LDO, no level translator for the RS-232 side — the charge pump generates the ±5.5 V swing internally from whatever rail you feed it. That saves a couple of passives and one regulator slot on the BOM. ## Package and footprint — 20-SSOP Housed in a 20-SSOP (5.30 mm body width), surface-mount only. ## Receiver hysteresis — noise margin on the bus Receiver hysteresis is 300 mV.","metaTitle":"MAX3222CDB Texas Instruments RS-232 Transceiver, 250 kbps","metaDescription":"MAX3222CDB RS-232 transceiver from TI, full duplex, 2/2 drivers/receivers, 250 kbps data rate, 3V to 5.5V supply, 20-SSOP package, 0°C to 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":"250kbps","Mounting Type":"Surface Mount","Package / Case":"20-SSOP (0.209\\\", 5.30mm 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-SSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2dd0c720be57623e93e05eecf9ce44ce.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3222CDB/alternatives.json"},"ai":{"faq":[{"question":"Can MAX3222CDB be used with a 5V supply?","answer":"The internal charge pump generates the RS-232 voltage levels from that supply without any external components."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX3222CDB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX3222CDB when reusing this data.
