RS-485/RS-422 half-duplex transceiver for industrial bus lines
The MAX3443EESA+T is a single-channel half-duplex transceiver supporting both RS-422 and RS-485 protocols, with one driver and one receiver integrated in an 8-SOIC package. Rated for 10 Mbps data rate, this part handles the signaling speed for Profibus, Modbus RTU, and other fieldbus links running at the upper end of the RS-485 band.
Receiver hysteresis and noise margin for long cable runs
25 mV of receiver hysteresis filters out noise coupled onto long twisted-pair cables, preventing the receiver from toggling on differential noise below that threshold. The half-duplex bus architecture means the driver and receiver share the same pair of wires; the transceiver's output enable must be managed by the host controller to avoid bus contention.
Active lifecycle and compliance documentation
The part is ROHS3 Compliant, meeting the EU RoHS directive for lead-free soldering processes.
8-SOIC footprint for surface-mount assembly
Available in Tape & Reel (TR) and Cut Tape (CT) options — the TR suffix on the order code indicates reel packaging for automated pick-and-place lines.
