This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

These devices extend the RS-485 portfolio with a family of full-duplex transceivers with robust 3.3-V drivers and receivers and high levels of ESD protection.

The ESD protection includes > ±30-kV HBM and > ±12-kV IEC61000-4-2 contact discharge.

The large receiver hysteresis of the SN65HVD7x devices provides immunity to conducted differential noise and the wide operating temperature enables reliability in harsh operating environments.

Key Features

  • 1 1/8 Unit-load options available.
  • Up to 256 Nodes on the bus.
  • Bus I/O Protection.
  • > ±30-kV HBM protection.
  • > ±12-kV IEC61000-4-2 Contact discharge.
  • > ±4-kV IEC61000-4-4 Fast transient burst.
  • Extended industrial temperature range:.
  • 40°C to 125°C.
  • Large receiver hysteresis (70 mV) for noise rejection.
  • Low power consumption.
  • < 1.1-mA Quiescent current during operation.
  • Low Standby supply curr.
