It pushes 25 Mbps on the bus, which puts it in the high-speed tier for industrial serial links — think encoder feedback, motor-drive comms, or multi-drop sensor networks where the update rate needs to stay tight. The 20 mV of receiver hysteresis cleans up noise on long cable runs without external filtering. ## Supply voltage flexibility — one part for 1.8 V, 3.3 V, or 5 V rails The 1.71 V to 5.5 V supply range means this transceiver can sit on a 1.8 V logic bus without a level shifter, or run straight from a 5 V industrial supply. That flexibility simplifies BOM consolidation: one qualified part number covers multiple board variants across different voltage domains. The full-duplex topology also means separate transmit and receive pairs, so no direction-pin toggling — useful for point-to-point links where the MCU's UART expects separate TX and RX lines. ## Industrial temperature range and active lifecycle Rated for -40°C to 105°C, the MAX14858GWE+ is built for factory-floor enclosures, outdoor telecom cabinets, and under-hood automotive auxiliary modules. For designs that need a second-source hedge, the wide supply and full-duplex pinout are shared by a few competitors in the same 16-SOIC footprint — qualify one and you have a drop-in backup.","metaTitle":"MAX14858GWE+ RS-485/RS-422 Transceiver, 25 Mbps, 16-SOIC","metaDescription":"Maxim MAX14858GWE+ full-duplex RS-485/RS-422 transceiver, 25 Mbps data rate, 1.71 V to 5.5 V supply, -40°C to 105°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"25Mbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.71V ~ 5.5V","Receiver Hysteresis":"20 mV","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.09","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$12.09000","currency":"USD"},{"qty":10,"price":"$11.11100","currency":"USD"},{"qty":25,"price":"$10.65040","currency":"USD"},{"qty":100,"price":"$9.38390","currency":"USD"},{"qty":250,"price":"$8.92336","currency":"USD"},{"qty":500,"price":"$8.34764","currency":"USD"},{"qty":1000,"price":"$7.65681","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX14856-MAX14858.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX14858GWE+ suitable for 5V systems?","answer":"Yes. The supply voltage range of 1.71 V to 5.5 V covers 5 V operation directly, so it can interface with 5 V logic or industrial 5 V rails without an external regulator."},{"question":"Does MAX14858GWE+ support half-duplex operation?","answer":"No — this is a full-duplex transceiver with separate driver and receiver paths. For half-duplex RS-485 buses you would need a part with a direction-control pin and shared differential pair."},{"question":"What is the typical propagation delay of MAX14858GWE+?","answer":"The evidence does not list a typical propagation delay figure. For timing closure analysis, refer to the manufacturer's datasheet for driver and receiver propagation delay specs."},{"question":"Can MAX14858GWE+ be used as a drop-in replacement for SN65HVD3082?","answer":"Not directly — the SN65HVD3082 is a half-duplex transceiver, while the MAX14858GWE+ is full-duplex. The pinouts and bus wiring differ. For a full-duplex replacement, compare the supply range and data rate against the specific TI part number."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX14858GWE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX14858GWE when reusing this data.
