What are the key features of PTHVD1419DR?
- Integrated surge protection on bus pins compliant with IEC 61000-4-5, eliminating external TVS components in RS-485 field installations
- Dual-supply 3.3 V to 5 V operation with differential Schmitt trigger receiver input for reliable communication in noisy industrial environments
- EIA-485-A/TIA-485-A compliant half-duplex driver/receiver pair in compact 8-pin SOIC package for space-constrained RS-485 node designs
What is PTHVD1419DR used for?
PTHVD1419DR is ideal for industrial RS-485 networks such as Modbus RTU, BACnet MS/TP, and PROFIBUS DP where long cable runs and harsh electromagnetic environments demand robust surge protection. Building automation controllers, motor drives, and smart meters benefit from its integrated surge compliance, reducing board-level protection component count. It also suits outdoor or field-installed equipment exposed to lightning-induced transients on the communication bus lines.
