SN65HVD1792 - RS-485 Transceiver

Download the SN65HVD1792 datasheet PDF. This datasheet also covers the SN65HVD1785 variant, as both devices belong to the same rs-485 transceiver family and are provided as variant models within a single manufacturer datasheet.

General Description

These devices are designed to survive overvoltage faults such as direct shorts to power supplies, miswiring faults, connector failures, cable crushes, and tool mis-applications.

They are also robust to ESD events, with high levels of protection to human-body model specifications.

Key Features

  • Bus-Pin Fault Protection to:.
  • > ±70 V ('HVD1785, 86, 91, 92).
  • > ±30 V ('HVD1787, 93).
  • Common-Mode Voltage Range (.
  • 20 V to 25 V) More Than Doubles TIA/EIA 485 Requirement.
  • Bus I/O Protection.
  • ±16 kV JEDEC HBM Protection.
  • Reduced Unit Load for Up to 256 Nodes.
  • Failsafe Receiver for Open-Circuit, Short-Circuit and Idle-Bus Conditions.
  • Low Power Consumption.
  • Low Standby Supply Current, 1 μA Typical.
