If your design needs 1 Mbps or more, you're looking at a different family (MAX3232E or MAX3221E). For the bulk of industrial serial ports, 250 kbps is the sweet spot — it keeps EMI low and the slew-limited output meets the RS-232 standard without extra filtering. ## 2/2 driver/receiver count and full duplex Two drivers and two receivers mean a full set of TX/RX lines plus hardware handshake (RTS/CTS) in one IC. Full-duplex operation lets both directions talk simultaneously, which matters for modems, multi-drop polling, or any link that can't half-duplex the turnaround. The 300 mV receiver hysteresis cleans up noisy lines — a common headache on long cable runs in industrial environments. The 20-SSOP (0.209-inch body width, 5.30 mm) is a fine-pitch but hand-solderable package. MSL rating is typically 1 for this family, so no bake-out needed before reflow unless the bag has been open for weeks. The narrow body means the part sits low and doesn't shadow adjacent components during hot-air rework.","metaTitle":"MAX3222IDB RS-232 Transceiver, 250 kbps, 20-SSOP","metaDescription":"MAX3222IDB is a full-duplex RS-232 transceiver with 2/2 drivers/receivers, 250 kbps data rate, 3 V to 5.5 V supply, industrial temp.","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":"-40°C~85°C","Supplier Device Package":"20-SSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2dd0c720be57623e93e05eecf9ce44ce.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3222IDB/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MAX3222IDB and MAX3232?","answer":"If your serial link needs to run above 250 kbps, the MAX3232 is the faster sibling.
