The 250 kbps data rate is the ceiling for this transceiver, matching the original RS-232 specification's practical limit for cable runs up to about 15 meters. For UARTs running at 115.2 kbps or 230.4 kbps, there is margin on the eye diagram; for designs pushing 1 Mbps or higher, this part is not the fit. The 300 mV receiver hysteresis provides noise rejection on the incoming signal, which helps maintain data integrity in electrically noisy environments like motor-drive cabinets or factory floors. The 3V to 5.5V supply range means the same BOM line works in a 3.3V-only system or a legacy 5V backplane — no separate regulator needed for the serial interface.","metaTitle":"MAX3222IPWRE4 Texas Instruments RS-232 Transceiver, 250 kbps","metaDescription":"TI MAX3222IPWRE4 RS-232 transceiver, full duplex, 2/2 drivers/receivers, 250 kbps data rate, 3V-5.5V supply, -40°C to 85°C, 20-TSSOP.","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-TSSOP (0.173\\\", 4.40mm Width)","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-TSSOP","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/MAX3222IPWRE4/alternatives.json"},"ai":{"faq":[{"question":"Is MAX3222IPWRE4 a direct replacement for the base MAX3222?","answer":"Yes.
