At 250 kbps this transceiver handles standard RS-232 rates for legacy peripherals, barcode scanners, and serial debug ports. The 300 mV receiver hysteresis is a practical guard against noise on longer cable runs inside a cabinet. The ROHS3 compliance (lead-free) is current for global shipping. ## 20-TSSOP footprint — what it connects to The 20-TSSOP package (4.40 mm width, 0.65 mm pitch) is a standard fine-pitch surface-mount footprint shared across many RS-232 transceivers in this family.","metaTitle":"MAX3222IPWR RS-232 Transceiver, 2/2 Drivers, 250kbps","metaDescription":"Texas Instruments MAX3222IPWR full-duplex RS-232 transceiver. 3V to 5.5V supply, 250kbps data rate, 2/2 drivers/receivers, -40°C to 85°C, 20-TSSOP package.","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-TSSOP (0.173\\\", 4.40mm 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-TSSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1000","priceTiers":[{"qty":1,"price":"$2.10000","currency":"USD"},{"qty":10,"price":"$1.88400","currency":"USD"},{"qty":25,"price":"$1.77680","currency":"USD"},{"qty":100,"price":"$1.51400","currency":"USD"},{"qty":250,"price":"$1.42156","currency":"USD"},{"qty":500,"price":"$1.24388","currency":"USD"},{"qty":1000,"price":"$1.03064","currency":"USD"},{"qty":2000,"price":"$1.00583","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2dd0c720be57623e93e05eecf9ce44ce.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3222IPWR/alternatives.json"},"ai":{"faq":[{"question":"What are the differences between MAX3222IPWR and MAX3222E?","answer":"The MAX3222E variant typically adds ±15 kV ESD protection on the RS-232 bus pins, while the base MAX3222IPWR does not carry that enhanced ESD rating."},{"question":"Can MAX3222IPWR be used as a drop-in replacement for MAX232?","answer":"Not directly — the MAX232 uses a 16-pin DIP/SOIC package and a different pinout, while the MAX3222IPWR comes in a 20-TSSOP.
