What are the key features of PTHVD1406DR?
- Automatic direction control eliminates the need for a dedicated enable signal, simplifying half-duplex RS-485 firmware and PCB routing
- ±8 kV IEC 61000-4-2 ESD protection on bus pins guards transceiver nodes in harsh industrial cable environments
- Operates from 3.3V or 5V single supply with 500 kbps maximum data rate, compatible with both legacy 5V and modern 3.3V MCU interfaces
- Differential Schmitt-trigger receiver input improves noise immunity on long cable runs with common-mode voltages from -7V to +12V
- Compact 8-pin SOIC (SOIC-8) footprint with low 0.1 mA high-level input current reduces drive requirements on microcontroller GPIO lines
What is PTHVD1406DR used for?
The PTHVD1406DR is designed for industrial networks, building automation, and RS-485 multi-drop bus systems where half-duplex communication at up to 500 kbps over twisted-pair cable is required. Its auto-direction control and ±8 kV ESD protection make it ideal for field instrument nodes, HVAC control panels, and energy meters that must withstand electrical surges from long cable runs in noisy factory environments.
