The Analog Devices MAX13432EESD+ is a full-duplex RS422/RS485 transceiver in a 14-SOIC package.
The 500kbps data rate is the headline selection parameter for this transceiver. Full-duplex operation means the driver and receiver are active simultaneously over separate twisted pairs. This avoids the turnaround dead time inherent in half-duplex RS485 designs, making it the right choice for point-to-point links where continuous bidirectional data flow matters — PLC-to-drive links, remote I/O racks, and serial backplanes. In electrically noisy environments — motor drives, VFD cabinets, welding equipment — this built-in margin reduces false triggering from coupled noise without external filtering components.
No PCN or LTB date is published for this part. For long-life industrial designs, this means the supply outlook is stable and no immediate requalification is needed.
