Data rate is rated at 250 kbps — a moderate speed suited for fieldbus links, Modbus networks, and other low-to-medium throughput applications where signal integrity over longer cable runs matters more than raw throughput. Operating temperature spans -40°C to 85°C, covering industrial environments such as factory floors, outdoor telecom cabinets, and HVAC controllers, but not extended automotive or downhole applications. Receiver hysteresis is specified at 25 mV, which helps reject noise on the bus lines in electrically noisy environments without external filtering.","metaTitle":"MAX3440EEPA+ RS-485/RS-422 Transceiver, Half-Duplex","metaDescription":"MAX3440EEPA+ RS-485/RS-422 transceiver, half-duplex, 250 kbps data rate, 1/1 driver/receiver, 8-PDIP, -40 to 85°C, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Transceiver","Duplex":"Half","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"250kbps","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Receiver Hysteresis":"25 mV","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-PDIP","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.66","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.66000","currency":"USD"},{"qty":10,"price":"$8.72900","currency":"USD"},{"qty":25,"price":"$8.32360","currency":"USD"},{"qty":100,"price":"$7.22720","currency":"USD"},{"qty":250,"price":"$6.90232","currency":"USD"},{"qty":500,"price":"$6.29332","currency":"USD"},{"qty":1000,"price":"$5.48127","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX3440E-MAX3444E.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX3440EEPA+ RoHS compliant?","answer":"Yes, it is ROHS3 compliant."},{"question":"What is MAX3440EEPA+'s listed duplex?","answer":"Half-duplex — the driver and receiver share the same bus lines, so direction control is handled via the driver enable pin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX3440EEPA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX3440EEPA when reusing this data.
