The lineup includes the MxL83232, MxL83233, MxL83234, MxL83235, and MxL83236, addressing the performance and reliability demands of modern industrial control systems.
The MxL8323x transceivers support data rates from 500 kbps to 50 Mbps, enabling system designers to balance performance, noise immunity, and EMI reduction across a wide range of industrial control applications. Multiple speed options within the family allow engineers to select the optimal device for each node, simplifying platform reuse while meeting diverse system requirements.
News Highlights
- Scalable Performance: Data rate options from 500kbps to 50Mbps across the MxL8323x family.
- Harsh Environment Robustness: Designed to withstand ±4kV IEC 61000‑4‑4 Electrical Fast Transient (EFT) events, ±8kV IEC 61000-4-2 contact ESD, and ±15kV air-gap ESD. An extended ±15V common‑mode range enables stable communication in the presence of ground offset differences.
- System Flexibility: 3.0V to 5.5V supply operation with a 1.65V–5.5V logic‑level interface for variety of embedded systems and SoCs.
- Network Scalability: 1/8‑unit‑load receiver input impedance supporting up to 256 nodes
- Industrial Operating Range: –40°C to +125°C with ±15V common‑mode capability.
- Additional Benefits: Slew rate control, hot swap glitch protection, and ultra-low power shutdown modes
These capabilities make the MxL8323x family well suited for applications including smart factory automation, high-performance motor drives, HVAC systems, industrial computing, building security, and smart grid infrastructure.
The global RS-485 transceiver market remains strong, with a total addressable market of approximately $200 million in 2026 and projected to expand at a 5.4% CAGR through 2033, driven by increasing industrial automation, motor drive control, and smart grid infrastructure deployments, according to Data Insights Market, “RS485 Transceiver IC Market Expansion Growth Outlook 2026–2034.”
“Industrial systems require robust communication links that can withstand high noise, wide voltage variations, and challenging environmental operating conditions,” said Dr. Amit Bavisi, Senior Vice President and General Manager, Analog & Mixed Signal Business Unit at MaxLinear. “The MxL8323x family, which is currently ramping in production at several customers, addresses many of these requirements with scalable data rates up to 50Mbps, high ESD and EFT immunity, broad voltage‑level compatibility, and support for large multi‑drop networks. The flexible 1.65V to 5.5V logic‑level interface enables direct connection to modern low‑voltage MCUs, helping reduce system complexity, power consumption, and PCB area in space‑constrained industrial designs.”
“The MaxLinear MxL83234 delivers the precision and reliability our industrial customers depend on for advanced motor encoder systems,” said Masahiro Ogura, Director, IN Product Department 3, Industrial Solution Company, Tokyo Electron Device Limited. “We’re excited to support engineers with a solution that simplifies design while enhancing performance across demanding automation environments.”
