RS-485 interface integrated circuit with fault protection for communication over long distances

SN65HVD1781P General Description

The SN65HVD1781P is a robust and reliable transceiver designed to withstand overvoltage faults and ESD events, making it suitable for a wide range of industrial applications. With its ability to survive direct shorts to power supplies, mis-wiring faults, and connector failures, this device provides a high level of protection for communication systems. In addition, its wide common-mode voltage range makes it ideal for multipoint applications over long cable runs, offering flexibility and scalability in networking environments

Key Features

  • SN65HVD1781P is a RS-485/RS-422 transceiver with a high data rate of up to 52 Mbps, low power consumption, and wide operating voltage range of 3V to 3
  • 6V
  • It has a fail-safe receiver to ensure a high-level output when the input is open or shorted
  • It also has a low driver output impedance for improved signal integrity
  • Application
