Half-duplex RS-485 transceivers from MaxLinear offer extended ESD and EFT protection to ensure reliable communication in industrial environments. The MxL8312x and MxL8321x families include nine product SKUs with three speed options—250 kbps, 500 kbps, and 50 Mbps—and three package variants, including small 3×3-mm types.

These families expand MaxLinear’s portfolio with mid- and high-tier products alongside the MxL8310x and MxL8311x lineup of RS-485 transceivers. Smaller form-factor packages, higher speeds, and enhanced system-level ESD and EFT protection make them well-suited for delivering high performance under harsh conditions. Key applications include factory automation, industrial motor drives, robotics, and building automation.
The transceivers’ bus pins tolerate up to ±4 kV of electrical fast transients (IEC 61000-4-4) and up to ±12 kV of electrostatic discharge (IEC 61000-4-2). A supply range of 3.3 V to 5 V supports reliable operation in systems with potential power drops, while an extended common-mode range of up to ±15 V ensures stable communication over long distances or in applications with significant ground plane shifts between devices. MxL83214 devices are cable of supporting 50-Mbps data rates with strong pulse symmetry and low propagation delays.
In addition to conventional 4.9×3.9-mm NSOIC-8 packages, the transceivers are offered in 3×3-mm MSOP-8 and VSON-8 packages. The MxL83121, MxL83122, MxL83211, MxL83212, and MxL83214 are available now.
