Key Features
- Half-duplex RS-485/RS-422 operation with automatic direction control eliminates external flow-control logic
- Wide supply range of 3.3V to 5V supports mixed-voltage system designs
- ±12-kV IEC ESD protection on bus pins ensures robust field deployment in harsh industrial environments
- Up to 12-Mbps data rate enables high-speed multi-drop network communication
Applications
The THVD1426DR is well suited for industrial automation networks, factory floor RS-485 buses, and PLC/DCS communication links where reliable half-duplex data transfer at up to 12 Mbps is required. Its wide supply voltage range and auto-direction control make it equally effective in building automation, smart metering, and HVAC control systems. The high ESD rating also suits motor drive interfaces and other electrically noisy environments.
