This transceiver requires a 5 V rail; it is not specified for 3.3 V operation."},{"question":"What is the difference between MAX3443ECSA+ and MAX3443EESA+?","answer":"The two parts are functionally identical — same transceiver, same 10 Mbps data rate, same 8-SOIC package. The difference is temperature grade: the MAX3443ECSA+ is rated 0°C to 70°C (commercial), while the MAX3443EESA+ is rated -40°C to +85°C (industrial). For outdoor, unheated, or automotive-adjacent environments, use the EESA+ variant."},{"question":"Is MAX3443ECSA+ equivalent to SN65HVD10?","answer":"Both are 5 V half-duplex RS-485 transceivers in 8-SOIC, but they are not drop-in equivalents without a pinout check. The SN65HVD10 from TI is a functional peer with similar data rate and supply range. Confirm the enable-logic polarity and receiver-disable behaviour against your schematic before substituting; the Maxim part uses a different enable scheme on the driver and receiver pins."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX3443ECSA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX3443ECSA when reusing this data.
